- Fix Util.UnixTimeSinceEpoch:

  * Unix epoch starts at midnight, not at 8:00am
  * All date/time handling should be done in UTC in the server, not in
    the local timezone.
  * Refactor out repeated computation of a constant value
- Added setting of CreationTime to some places where inventoryitems
  are created
This fixes Mantis#2390.
