Describe the issue

Entry timestamps in the logger are incorrect when the system time zone's UTC offset is not on an hour boundary (e.g. Newfoundland Time Zone at -03:30 UTC, Nepal Standard Time at +05:45 UTC).

Steps for anyone to reproduce the issue

1. Set the system time zone to one of the above-mentioned.
2. Open the logger, and take any action that adds new entries to the logger (e.g. open https://github.com/gorhill/uBlock/ in a new tab)
3. Notice the timestamps of the new logger entries (specifically the minute value) do not match the current time.

Fix seems trivial: using getUTCMinutes() rather than getMinutes() in line 546 of /src/js/logger-ui.js gives the correct timestamp, since the offset is already applied via setTime().
