I've got code that does time tracking for employees. It creates a counter to show the employee how long they have been clocked in for.
This is the current code:
start_time = Time.parse(self.settings.first_clock_in) total_seconds = Time.now - start_time hours = (total_seconds/ 3600).to_i minutes = ((total_seconds % 3600) / 60).to_i seconds = ((total_seconds % 3600) % 60).to_i
This works fine. But because Time is limited to the range of 1970 – 2038 we are trying to replace all Time uses with DateTimes. I can't figure out how to get the number of seconds between two DateTimes. Subtracting them yields a Rational which I don't know how to interpret, whereas subtracting Times yields the difference in seconds.
NOTE: Since Ruby 1.9.2, the hard limit of Time is removed. However, Time is optimized for values between 1823-11-12 and 2116-02-20.
