I would just include date information in the timestamp. Any timestamp you get from a library will already have that information in it anyway. The real question is, why are you doing this yourself. Surely, whatever language you use has a date comparison library and can handle this situation with a simple method. Reinventing the wheel, especially with a domain as intractable as dates and times, is a 'bad' idea. Let us know what you come up with though.

Hi guys,
Programmers, what algorithm would you use to check that a given time (current timestamp in 24hr) is within a preset start and end times and if so, do specific stuff?
Scenario:
StartTime = 0600 EndTime = 1800
TimeNow = 0950
An algorithm like
If TimeNow >= StartTime and <= EndTime then allow
would work
However, this will not work if the Start/End time spans across 2 days:
StartTime = 1800 EndTime = 0600
TimeNow = 0550
Using the logic will fail yet 0550 is logically within the preset timeframe
