I should have posted this yesterday, but I didn't... So imagine it was dated 02 Apr 2000.
Days with less than 24 hours really suck. I spent the better part of the afternoon fighting a bug in gnomecal which caused a crash (SIGFPE) on startup --- fussy computer, didn't like dividing by zero. :) It seems there is a special case which prevents the divide by zero 364 days of the year, but on the day when DST starts (and the assumption # of hours/day == 24 is not applicable), it doesn't trigger leading to the crash.
The tricky part was figuring out a fix: I am pretty sure the entire daylight savings time logic which was patched in a year or so ago is broken, but I need to do some more checking/testing to prove it...
On the other hand, this did show that gnomecal has users: I have now received in excess of fifteen different reports of this bug, which means that at least that many people tried to start gnomecal yesterday. :)
