where exactly is the problem?
the new clock can't be started directly, you have to copy it to "/usr/bin/worldclock" AFTER renaming the old!
The original clock is a link to maemo-invoker.

Here it works quiet good, the inactive alarms were previously not displayed correctly (instead of the time only a long number was displayed...) also the days when the alarms should occurs weren't displayed only a number was shown here...
But the replacement clock now is showing the alarms correctly! Thx for that cepiperez!
