Hi Michel,

SECONDS() only returns the number of seconds passed since midnight.

Using DATETIME() should solve this problem.
dtStartTime   = {04/07/2001 11:59:59 PM}
dtEndTime     = {05/07/2001 12:00:01 AM}
nTotalSeconds = dtEndTime - dtStartTime
The above example will return 2 seconds.

Please note that I'm using a BRITISH date format.

Hope this helps,
Gavin...

>This is a strange situation I wanted to talk about. The Universal Thread is using the Visual FoxPro Seconds() function to calculate the amount of time required to process a transaction. When the transaction is completed, we issue REPLACE LAP WITH SECONDS()-gnTime where gnTime contains the Seconds() start time. So, this is usually returning 0 to 1 second lap time as this is about what it takes to process a Universal Thread transaction.

After a few investigations, I finally found that the transaction started in the last second of the day and ended in the first second of the new day. So, I added a condition to detect if the SECONDS() is greater than gnTime in order to avoid that. But, the weird situation is that this is unlikely to happen as it requires a lot of precision. I had it about 4 times in the first 6 months of 2001. <s>
