[RFC PATCH 0/1] adding user.hideTimezone for setting UTC timezone

Discussed with Jonathan and Junio regarding whether we should support letting user specify timezone or restricted to UTC only. There was no defnite conclusion. I think it's a good idea to start with this implementation which might result in the change landing or e.g. a documentation change.

The patch add checking for user.hideTimezone and change environment variable TZ to UTC in the beginning of cmd_commit if it's true. As a result, when calculating timezone offset in datestamp(date.c) would result in 0.
