[evolution-patches] patch for 301350 (calendar)

[Rodrigo Moya <rodrigo novell com>]

This should fix Michael's problems with the alarm daemon and suspending
a laptop over midnight.

Michael, not sure if you're running a source code installation. If so,
could you apply and test the attached patch? It seems to work for me,
but to make sure it would be interesting to have it tested.
