Subject: Timestamps and finding the difference (mm:ss)

(using ANT 1.7 on Windows XP sp3)

I like to get the timestamp before a task is executed, and one when the task is finished,
and then calculate the difference to get the duration of the task?

I’d like to do this so I can see how long certain tasks take to run.

I see that I can create a timestamp property as follows:

<tstamp><format property=”timeStart” pattern=”hh:mm:ss” /></tstamp>
<tstamp><format property=”timeEnd” pattern=”hh:mm:ss” /></tstamp>

But can't find info (easily) on how to do some math to get the difference in time. Any insight
would be appreciated.
