Fix commit time timezones

[mrkeuz]

Currently, commit time set as UTC time. So here fix for this.

It was very much by design committing in UTC, is that causing problem?

I'm not faced with some problems. But it little confused that you commit just now, but git log show you date corrected by timezone offset.

I.e. my time zone +03:00, but after commit git log shows that commit taken three hours ago.

So currently commit date is just wrong.

Edit:
If I understand correctly datetime.utcnow() return datetime object without tz info and so treated as local time (see docs below). If timezone i.e. +03:00 you get datetime object pointed to now - tz offset.

As well as datetime treated as local, and it pointed to datetime with some offset in result you get wrong timestamp.

See: https://docs.python.org/3/library/datetime.html#datetime.datetime.utcnow
