time stamp to number conversion

[Sam Mason]

Hi All,

I notice in Labview 7.0 the 'Get Date/Time to Seconds' and 'Seconds to Date/Time' now output a Time Stamp rather than actual seconds.
There is a 'To Time Stamp" standard vi in the conversion pallet that converts a number (seconds) to a time stamp but I really need to convert from a Time Stamp to real seconds.
Does anyone have a vi that might do this or is there something already in LabVIEW 7.0 I have overlooked?

Many Thanks in Advance for your help.

Use the Get Date/Time in Seconds widget.
Connect it to a "To Double Precision Float" conversion to get the time (since 1904) in seconds.

Thank you very much for the help! 🙂

This does not work in LV 8. The result of the conversion is still a date time rec but now having doubles in stead if ints.

If I  need days I take the result and divide by 86400, the number of seconds in a day.  If you are working with UTC time stamps and you want to convert it dividing by the units it the only way i have seen.

What do you mean when you say you need seconds from the time stamp?  I have some time VI I have made that may be of some help if I understood what you were looking for.

Best Regards

You are going to have to post an example where the conversion does not work.

Dennis,

You're right! Think I was mixing up Time Stamp and Date Time Rec.

Thanks.
