This program is a great idea, but the timer is inaccurate. I compared the "work-timer" timer to my computer's clock (which is hooked in with the atomic clock in Boulder, Colorado). Work-timer slowed down by an average of 1 second for every minute. So that means if you worked 40 real hours, work-timer would tell you that you only worked 30 hrs. and 20 minutes. If you worked 40 hrs. a week for one year, at the end of the year you would have lost 34 hrs. and 20 minutes. That's the equivalent of 4.33 days off! As for me, I'm going to try a different "timer" program.
