"This is your interpretation and I disagree.
If I set up a timer with a 24 hour interval, which should go off
everyday at 6:00 AM, then I expect that this timer does this even when
the clock is set e.g. by daylight saving. I think, that this is a
completely valid interpretation and makes a lot of sense from a
practical point of view. The existing implementation does it that way
already, so why do we want to change this ?"
Please do not hardcode anywhere 1 day = 24h or something like this.
Relative timers should stay relative not depend on DST.
If someone needs a timer that sets of everyday at the same (legal) time,
make him ask for everyday at that time not one time + n x 24h.
Some processes need an exact legal hour
Other processes need an exact duration
In a DST world that's not the same thing at all - don't assume one or the
other, have coders request exactly what they need and everyone will be
happy.
I can tell from experience trying to fix code which assumed one day = 24h
is not fun at all. And yes sometimes the difference between legal and UTC
time matters a lot.
