    timing until event - computationally expensive ?

    i need to run a seconds timer for a certain event, this may run for upto a month, so im thinking this is quite expensive and generally a poor way to do it. Is there another way, i suppose i could match a time against the system clock, any feedback appreciated.

    How about loading the current calendar time into a tm struct and calculating the timer from a saved value when you need it? That would be a lot more efficient than continually updating the timer if you don't look at it very often :-)
