Question

Here is what I am struggling with.

I have to determine whether current time, time_t, is overlapping with a triplet of
day of week (0 Sunday to 6 Saturday)

start time = minutes from midnight 
end time = minutes from midnight

So 1/17/2012 13:00:00 does overlap with 2(tuesday) 600, 900
1/17/2012 13:00:00 does not overlap with 1(monday) 0, 1000

Any thoughts on how to implement this?

Thanks

Answer 1

Convert your time_t to a struct tm using localtime_r (or localtime_s on Windows). Then you will have day of the week (in tm_wday) and the various other values you can compare against.
