The answer to this question is probably going to be "no", but I'm going to try anyway.
Is there a clock-app, preferably an android app, (or an actual physical watch, though this is not the forum for that), that has a non-standard day-length such as 23 hours? 23 hours would be nice, but even better would be one that has an adjustable duration.
Let me be clear what I mean:
one hour lasts the same amount of time on this clock as on standard clocks,
but there are only 23 hours in a single "day" (or preferably, an adjustable amount). That means that one "day" on this clock lasts 23\24ths the time that a normal day lasts, so that after one "day" on this clock, the earth has only made 23/24ths of a rotation. That means that if it now says 14:00 on both a normal clock and this weird clock, then 24 hours later it will say 14:00 on the normal clock, and 15:00 on the weird clock. 48 hours it will say 14:00 and 16:00, etc.
I want this in order to regulate a shorter sleep-cycle.
Is there a way to get this? I obviously already searched the app-store and couldn't find anything since this is obviously not a commonly desired thing.
