Time zones lost when upgrading from Redmine 1.4 to 2.0
It seems that previous versions of Redmine stored times in database in local time. In 2.0 it stores it in UTC. This causes all old times to be offset by the time zone. e.g. A task I entered right before the upgrade showed as being 5 hours old.
I just ran SQL to update the time stamps appropriately, but it might be nice to have this done automatically.
Here's the script I used (PostgreSQL):
select 'UPDATE ' || table_name || ' SET ' || column_name || ' = ' || column_name || '::timestamptz at time zone ''utc'' WHERE ' || column_name || ' < ''2012-05-22 10:40:00'';' from information_schema.columns where table_schema='public' and data_type like 'timestamp without time zone'
The hard-coded time is the time that the upgrade occurred so as not to update times from after the upgrade.

Rails 3 uses UTC timestamps by default. I've restored the previous behaviour for compatibility with Redmine 1.x in r9719 (timestamps stored in local timezone).
If you want to use UTC timestamps instead, just change
