Public bug reported:

When OpenERP generates resources for import into faces for resource
levelling, it emits the times as local time, while emitting and
interpreting UTC times for the task start and end dates.  This leads to
funny offsets in the resultant data.

Attached are two patches:

0002-resource-Convert-working-hours-to-UTC.patch is a rewrite of
resource.resource.calculate_working_calendar, which is time-zone aware.

In doing this, I discovered that Faces does _not_ like working hours
that span midnight.  (Our working hours are 0900-1700, and our local
time zone is UTC+10, leading to working ours of 2300-0700 UTC.)  Thus, I
have attached a second patch: 0001-faces-Fix-24-hour-and-end-at-
midnight-timespans.patch which corrects this behaviour.

The patch to faces has been submitted upstream:
https://sourceforge.net/tracker/?func=detail&aid=3487769&group_id=155221&atid=794937

Known issues:
- It assumes the user's local time zone, not the time zone of the resource
- It may break slightly where daylight savings time is involved.
