I agree with @Ashok, scheduling the task using cron jobs at the operating system level seems like the most intuitive way to approach @Lawi's problem. On Windows or other non UNIX-like O.Ss, use the "Scheduled Tasks" application or something similar. If I was to go with @Adam's way but write the system in JAVA I would use annotations <http://en.wikipedia.org/wiki/Java_annotation> which are just the opposite numbers to Python's decorators. I would have written the code to illustrate my point, but laziness as you all know is a virtue to any programmer worth his / her salt :-) Martin.

@Lawi, whether you like it or not, time IS tied to a date, because time cannot exist in the absence of a date.
So if users can only login between 1800Hrs on the current day and 0600Hrs the next day, the day still exists, only that its *rolling.*
Does that make sense?

@Adam not knowing the offending language, a concrete solution is as a pain so making sure he knows that specific fact('In the abstract') would have sufficed IMHO. [?]

@francis I think he's using the word 'timestamp' loosely as the time of day. But yes, as everyone agrees so far, just use the timestamp which has all the date information and then comparison is trivial.
Since we all seem to be having fun wasting time on a Thursday, I did it in Python for demonstration purposes. I set 'a' to now and then 'b' to now a few seconds later and then arbitrarily set 'c' to a time within the period. This is date-sensitive.

A timestamp will have all these details and you can extract the relevant details from it. I.e. datetime has both date and time. You can use the time or date where relevant. This is the essence of a timestamp.

@Lawi, does the start times change per day or are they sorta fixed at a preset time?
Say, every day at 0600Hrs is the start, and every day at 1800Hrs is the end
