Made tzcompile.jl compatible with Julia v0.4. …

Compatibility required that the following issue was fixed in Julia:
JuliaLang/julia#12003

Removed trailing whitespace.

Made use of joinpath.

Simplified initial pass in tzparse.

Minor changes to improve clarity.

Until in zone is only split when needed.

Revised parsedate function.

Refactored parts of zoneparse.

Renamed src files to match module names.

Moved TZCompile.jl to timezones/Olsen.jl

Made TimeZone types and update Olsen parser. …

Note: generate_tzinfo and generate_tzdata are now broken and need
to be updated.

Created ZonedDateTime type.

Changed offset precision to seconds.

Created local DateTime constructor for ZonedDateTime.

Fixed error with parsing zones.

Refactored ZonedDateTime constructor.

Broke up FixedTimeZone into two types. …

New types are OffsetTimeZone and DaylightSavingTimeZone. Change was
introduced to keep the UTC offset and the DST offset separate.

Added alternative ZonedDateTime constructor.

Created initial testcases.

Improved TZ database parser initial pass error handling. …

Link entries were being considered continuation lines. This issue
was noticed with parsing "Pacific/Honolulu". Code was restructured
to only treat lines that start with whitespace as continuation lines.
This change should now gracefully handle modifications the the TZ
database.

Major refactoring to the TZ database parser. …

Changes made to support all records provided by the TZ database
and additionally make debugging and testing easier.

Fixed problems encoutered with negative Time.

Switched Time to use seconds internally.

Added testcases for Olsen.parsedate.

Simplified processing of Rule's at param.

Attempting to get accurate timezone parsing.

Corrected issues noticedd with resolving timezones. …

Code works but is rather messy and needs refactoring.

Reduced iterations by ordering rules.

Refactoring resolve to be as clear as possible.

Update Time type to work comparing to Period types.

Made Time type a subtype of TimeType.

Updated parsing to deal with extremes of offsets/save.

Ensured that Zone array is sorted during resolve.

Minor refactoring and comments for resolve.

Changed flag to type Char and silenced debugging messages.

Various minor corrections.

Added function for loading all timezones.

Updated MINOFFSET.

Build now serializes TimeZone objects.

Created function that lists timezone names.

Refactoring build.jl to be more user friendly.

Added ZonedDateTime testcases and moved transition tests.

Fixed undefined variable in error message.

Added tests for obscure transition behaviours.

Testcase for skipping an entire day.

Created tests for behaviours with strange timezones.

Added support for TZ database Links.

Revised build process to handle download errors better.

Created ZonedDateTime constructor for switching a TimeZone.

Added equality comparisons for ZonedDateTimes.

Implemented arithmetic for ZonedDateTime.

Refactoring including switching FixedTimeZone to a concrete type. …

Previously we had OffsetTimeZone and DaylightSavingTimeZone as
subtypes of FixedTimeZone to avoid having to store the DST offset
for fixed timezones that didn't include this information. I don't
believe that the minor memory savings is worth the trouble currently
so I've remove the original two concrete types in favor of a single
type FixedTimeZone.

Additional changes:
- "dst_offset" and "utc_offset" removed.
- "total_offset" renamed to "offset".
- Added "localtime" and "utc" accessors for extracting a DateTime
- Removed sizehint! that wasn't necessary.

Parsing TZ data can now return FixedTimeZone.

Updated .gitignore file.

Added testcases that showcase ZonedDatetime associativity.

Made FixedTimeZone constructor for strings.

Implemented ZonedDateTime parsing. …

Current implementation overrides Base.Dates functions to include
additional functionality.

Updated DateFormat to dynamically lookup ids.

Updated Travis file and added badges.

Removed Compat import as we require 0.4 Base.Dates.

Updated build to retry download upon failure.

Refactored TZ data and the compiled directory into constants.

Added additional testcases to increase code coverage.

Added testcases for timezone_names.

Removed Transition from export list.

Added testcase coverage for negative arithmetic.

Fixed bug with from_utc keyword.

Moved Time type to separate file so that types could access extremes.

Improved testcase coverage.

Updated README.md to include basic usage.

Created trunc methods.

Added firstdayof*/lastdayof* adjusters.

Added several accessors.
