I've moved getalarms.pl to using DateTime. Contrary to the author's
recommendations I feel I need to do time manipulation in local time,
because SC alarms are local time.
Here are 2 test cases. Is this right ?
Code:

>> Case 1: on 29/March/2009, at 00:30:00 (Europe/Paris) -- normal to DST,
02:00 -> 03:00
