As long as you don't care about any units larger than days (months and 
years are variable-length and thus a little more work), you can just 
calculate the difference between two unix timestamps. They're just an 
integer number of seconds. Subtract the two, divide by 60 for minutes, 
3600 for hours, or 86400 for days.
