How can I make a timer that will record elapsed time up to 15 hours with a PCI-6503E DAQ card?

[Ethan]

I'm a beginner LabVIEW programmer, but need to take measurements of elapsed time from the start of data acquisition for up to 15 hours. I'm using a PCI-6503E card. Looking at examples on the web and LabVIEW, itself, I was only able to find a way to take time measurements with a DAQ card up to 167 s, unless two counters were tied together, but there are no instructions on how to do that. Could someone help me? Thanks.

I suggest you to look in the Resouce Library: inside it there is plenty of useful examples.
I found this VI with two cascaded timers in the Measurement hardware > Counter/Timer > Event/Time Measurement cathegory:

Hope this helps.
