How to get timestamp to start at zero hours?

[automasjon3ea]

Hi.

I'm building a software that logs values to excel.

The user can enter how long the test should run for, and the time elapsed should be set as a string in [hh:mm:ss]

The only problem is that the TimeStamp starts at 01:00:00 (beacuase of the 1904-issue i guess). How can I get the counter to start at 00:00:00, or maybe subtract the one hour in the begining so it starts at zero.

If you run the VI you'll understand what I mean.

Thanks!

Hi auto,

you have to use relative time instead of absolute time - see attachment...
