Subtracting to timestamps

[X_DOT]

Hi.

Iam pretty new to labview, and this is my first real project using labview.

I need to subtract 2 timestamp strings and get the difference between them. how do I do this?

I have attach'd af screenshot of my block diagram and hope you can help me.

(btw the project is to be handed in thuesday 16. dec -2008)

Sow Iam hoping to get a quick answer.

One possible way might be to convert the timestamp strings back into a LV timestamp then subtract them?

But I am sure others will come up with better ways of doing it.

On a side note; for a first project, well done.

Jens,

Why do you store the timestamps as strings?

If you keep the original timestamps in your array, you can use the "subtract" function and get the time difference in seconds.

In this case you will only have to convert the timestamps into strings just before displaying them.

hope this helps

You can also use "Scan from String" with the appropriate format specifier to convert a string to a timestamp.
