If we use now(), then server must run in UTC zone.
If we use utcnow(), server may run in any zone.

It is sometimes inconvenient, if the real server is not located in Zero
Time Zone, and can be used also for other purposes.

Title:
  [Trunk,6.1] Timezone ERROR in Scheduled Actions

Status in OpenERP Server:
  Incomplete

Bug description:
  In module BASE in file "\base\ir\ir_cron.py" function _run_job don't
  work properly.

  It take parametr "now" that calculated in local timezone like:

      now = datetime.now()

  and then compared in loop with "numbercall" that take from DB in UTC:

      while nextcall < now and numbercall:
                  ...
                  if numbercall:
                      nextcall += _intervalTypes[job['interval_type']](job['interval_number'])

  that cause "nextcall" calculated N times
  (N=TimeZoneShift/interval_number) and it make wrong interval between
  run actions.

  For example:
  ========================================================================
  current time = 09:00 (UTC)
  local current time = 13:00 (TZ = UTC+4) (current time of server)
  interval_number = 1 (from DB)
  interval_type = minutes (from DB)
  nextcall = 09:00 (from DB)
  Time to run scheduled action, that cause run function _run_job that calculate new "nextcall":

      nextcall = 09:00 + 00:01 (and repeat it 240 times)

      nextcall = 13:01

  So next run scheduled action will at 13:01 (UTC) or 17:01(local TZ). We have interval 4h and 1min, bat expect interval 1min!!!
  ========================================================================

  For correct work need

      now = datetime.now()

  change on

      now = datetime.utcnow()
