I'm getting 7 minutes not 6 for those dates. You may hit problem described in PRB: DateTime Subtraction May Not Produce an Exact Integer mskb #258998. Try to add rounding to fix the problem

function getminutes(elapsed_seconds)
return int((ROUND(elapsed_seconds,0) % 3600)/60)

>In Marcia's 1001 Things book, she lists a handy utility for calculating elapsed time by using the total seconds.

>function getminutes(elapsed_seconds)
>return int((elapsed_seconds % 3600)/60)

>I just now noticed that there is a problem with the way it is returning some values back to the calling program.

>Using 07/16/2007 08:42:30 as the start time and 07/16/2007 08:49:30 as the ending time, it returns 6 minutes, rather than 7. The days,hours & second functions seem to work just fine.
