I haven't used Scheduler, but Doug's stuff is generally quite solid: http://doughennig.blogspot.com/2007/04/scheduling-tasks.html

You can go ahead and try the VFP timer. I think if I were doing something that called for a 30 minute timer, rather than setting Interval to 30*60*1000, I might subclass Timer and add a StartTime property, then set that each time I do the task. Then I'd use the Timer set for 1 minute or something like that, and when it fires, check the current time against StartTime to see whether it's long enough.

That said, I've never tried to use a timer for anything longer than a minute or so, but it might be just fine. Have you tried just setting Interval and putting your code in the Timer method?
