hi friends,

I want to subtract two timeperiods say 04:46:30 from 02:30:22 and also the reverse should give the true result...

i want the result in milliseconds or in hh:mm:ss

Is there any java function for this.

and also function to convert the value from millseconds to hh:mm:ss.

thanks in advance..

Here's code that converts a begin ms and end ms into a duration string:

That actually looks an awkward way to do it. There is a far better way, but that would only give a clean result with a positive difference.
Consider Paul's rocket mass heater.
