Editor: Today I’m releasing version 1.0 of Date Difference, my first real app. It’s pretty simple, just give it two dates and/or times, and it tells you the length of time between them. It’s completely free, and you can Get it here.
There are preferences for what units to enable or disable (days, hours, minutes, and/or seconds), and it compensates for the disabled units with the next largest enabled unit (for example, if the difference between the dates is 1 day and 2 hours, but you disable days, then it becomes 26 hours).
Stuff I’m planning on adding include support for weeks, months, and years, as well as possibly iCal integration, as well as porting it to the iPhone (as soon as I get my developer membership).
UPDATE: It seems that version 1.0 of Date Difference only works on OS X Leopard, see here for more information!
