Time difference in seconds

Hello guys,

I am kind of a newbee...

Is there any way to know a time difference in seconds in standard ASP? The time difference will never be more than 100 seconds. I need to know that time difference between 2 times, but the problem I have is when the process runs, for example, from 11:59:25 PM to 00:00:34 AM (for the day change).

Thanks!

try:
<%

	

	function getTimeDiff(t1, t2)

		if isDate(t1) = false or isDate(t2) = false then

			getTimeDiff = "-"

		else

			dummyToday = DateSerial(2000,1,1)

			dummyToday2 = DateSerial(2000,1,2)

			

			d1 = CDate(t1)

			d2 = CDate(t2)

			

			if d1 > d2 then

				d1 = dummyToday + d1

				d2 = dummyToday2 + d2

				total = DateDiff("s", d1, dummyToday2) + DateDiff("s", dummyToday2, d2)

			else

				total = DateDiff("s", d1, d2)

			end if

			getTimeDiff = total

		end if

	end function

	

	response.write getTimeDiff("11:59:25 PM", "00:00:34 AM")

	

%>

here you are, you will use datediff

datediff("s","1/1/2009 11:59:25 PM","1/2/2009 00:00:34 AM")

Please keep in mind that my date format is MM/DD/YYYY
