"Naive" alarm clocks (those which don't know from timezones) break human expectations twice a year, because their users have to be awake to fix them (or make the clock itself out-of-whack with real civil time for the hours between fixing and the actual transition). For confirmatoin, ask your local priest / pastor about the twice yearly mixups among congregants whose clocks don't self-adjust for the DST boundary: some show up late / early for church *every* time the local zone changes. I'd be in favor of dropping "days" from timedelta, myself, for just this reason: if "1 day" is the same for your usecase as "24 hours", then just do the math yourself.
