+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+Want to contribute? Great! First, read this page (including the small print at
+the end).
+
+### Before you contribute
+
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement][CLA] (CLA), which you can do
+online. The CLA is necessary mainly because you own the copyright to your
+changes, even after your contribution becomes part of our codebase, so we need
+your permission to use and distribute your code. We also need to be sure of
+various other things—for instance that you'll tell us if you know that your code
+infringes on other people's patents. You don't have to sign the CLA until after
+you've submitted your code for review and a member has approved it, but you must
+do it before we can put your code into our codebase.
+
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+[CLA]: https://cla.developers.google.com/about/google-individual
+
+### Code reviews
+
+All submissions, including submissions by project members, require review. We
+recommend [forking the repository][fork], making changes in your fork, and
+[sending us a pull request][pr] so we can review the changes and merge them into
+this repository.
+
+[fork]: https://help.github.com/articles/about-forks/
+[pr]: https://help.github.com/articles/creating-a-pull-request/
+
+Functional changes will require tests to be added or changed. The tests live in
+the `test/` directory, and are run with `pub run test`. If you need to create
+new tests, use the existing tests as a guideline for what they should look like.
+
+Before you send your pull request, make sure all the tests pass!
+
+### File headers
+
+All files in the project must start with the following header.
+
+    // Copyright (c) 2017, the Dart project authors.  Please see the AUTHORS file
+    // for details. All rights reserved. Use of this source code is governed by a
+    // BSD-style license that can be found in the LICENSE file.

+one above, the

+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+This package provides a [`Clock`][] class which encapsulates the notion of the
+"current time" and provides easy access to points relative to the current time.
+Different `Clock`s can have a different notion of the current time, and the
+default top-level [`clock`][]'s notion can be swapped out to reliably test
+timing-dependent code.
+
+[`Clock`]: https://www.dartdocs.org/documentation/clock/latest/clock/Clock-class.html
+[`clock`]: https://www.dartdocs.org/documentation/clock/latest/clock/clock.html
+
+For example, you can use `clock` in your libraries like this:
+
+```dart
+// run_with_timing.dart
+import 'package:clock/clock.dart';
+
+/// Runs [callback] and prints how long it took.
+T runWithTiming<T>(T callback()) {
+  var stopwatch = clock.getStopwatch()..start();
+  var result = callback();
+  print("It took ${stopwatch.elapsed}!");
+  return result;
+}
+```
+
+...and then test your code using the [`fake_async`][] package, which
+automatically overrides the current clock:
+
+[`fake_async`]: https://pub.dartlang.org/packages/fake_async
+
+```dart
+// run_with_timing_test.dart
+import 'run_with_timing.dart';
+
+import 'package:fake_async/fake_async.dart';
+import 'package:test/test.dart';
+
+void main() {
+  test("runWithTiming() prints the elapsed time", () {
+    new FakeAsync().run((async) {
+      expect(() {
+        runWithTiming(() {
+          async.elapse(new Duration(seconds: 10));
+        });
+      }, prints("It took 0:00:10.000000!"));

 ## 1.0.0
 
-* Initial version.
+This release contains the `Clock` class that was defined in [`quiver`][]. It's
+backwards-compatible with the `quiver` version, and *mostly*
+backwards-compatible with the old version of the `clock` package.
+
+[`quiver`]: https://pub.dartlang.org/packages/quiver
+
+### New Features
+
+* A top-level `clock` field has been added that provides a default `Clock`
+  implementation. It can be controlled by the `withClock()` function. It should
+  generally be used in preference to manual dependency-injection, since it will
+  work with the [`fake_async`][] package.
+
+* A `Clock.stopwatch()` method has been added that creates a `Stopwatch` that
+  uses the clock as its source of time.
+
+[`fake_async`]: https://pub.dartlang.org/packages/fake_async
+
+### Changes Relative to `clock` 0.1
+
+* The top-level `new` getter and `getStopwatch()` methods are deprecated.
+  `clock.new()` and `clock.getStopwatch()` should be used instead.
+
+* `Clock.getStopwatch()` is deprecated. `Clock.stopwatch()` should be used instead.
+
+* The `isFinal` argument to `withClock()` is deprecated.
+
+* `new Clock()` now takes an optional positional argument that returns the
+  current time as a `DateTime` instead of its old arguments.
+
+* `Clock.now()` is now a method rather than a getter.

Subject: [PATCH 43/89] Update for repo best practices (dart-lang/clock#14)

- Use `pub.dev` links over `dardocs.org`.
- In example, follow `package:pedantic` style for function typed
  argument.
- Drop unused author field from pubspec.
- Use a simpler constraint on `package:meta` since the SDK constraint
  already prevents us from picking up older versions.

Subject: [PATCH 46/89] Remove unnecessary cast from clamp computation.
 (dart-lang/clock#21)

Now that the analyzer correctly computes the type of `int.clamp(int,
int)` as `int` (for libraries opted into null safety), we no longer
need to cast the result to an `int`.

Subject: [PATCH 50/89] Bump SDK constraints for pub (dart-lang/clock#25)

Use a 2.12.0 lower bound since pub does not understand allowed
experiments for earlier versions.

Use a 3.0.0 upper bound to avoid a warning in pub and to give some
flexibility in publishing for stable.

-Want to contribute? Great! First, read this page (including the small print at
-the end).
-
-### Before you contribute
-
-Before we can use your code, you must sign the
-[Google Individual Contributor License Agreement][CLA] (CLA), which you can do
-online. The CLA is necessary mainly because you own the copyright to your
-changes, even after your contribution becomes part of our codebase, so we need
-your permission to use and distribute your code. We also need to be sure of
-various other things—for instance that you'll tell us if you know that your code
-infringes on other people's patents. You don't have to sign the CLA until after
-you've submitted your code for review and a member has approved it, but you must
-do it before we can put your code into our codebase.
-
-Before you start working on a larger contribution, you should get in touch with
-us first through the issue tracker with your idea so that we can help out and
-possibly guide you. Coordinating up front makes it much easier to avoid
-frustration later on.
-
-[CLA]: https://cla.developers.google.com/about/google-individual
-
-### Code reviews
-
-All submissions, including submissions by project members, require review. We
-recommend [forking the repository][fork], making changes in your fork, and
-[sending us a pull request][pr] so we can review the changes and merge them into
-this repository.
-
-[fork]: https://help.github.com/articles/about-forks/
-[pr]: https://help.github.com/articles/creating-a-pull-request/
-
-Functional changes will require tests to be added or changed. The tests live in
-the `test/` directory, and are run with `pub run test`. If you need to create
-new tests, use the existing tests as a guideline for what they should look like.
-
-Before you send your pull request, make sure all the tests pass!
-
-### File headers
-
-When creating new source files, please copy the file header from 
-https://github.com/dart-lang/clock/blob/master/lib/clock.dart and update the year
-for the copyright to the current year.
-
-### The small print
-
-Contributions made by corporations are covered by a different agreement than the
-one above, the
-[Software Grant and Corporate Contributor License Agreement][CCLA].
