Scan from String with format specifier "%d_%d_%d_%d_%d" and then format the element back into a string with Format into String and "%d%d%d%d%d".

Alternatively you can also use the Search and Replace String with search pattern set to "_" and the replace string set to "" (empty string).

Hi Petros,

use ScanFromString to parse into a timestamp - see the help for all the supported format codes.

Then it's a simple subtraction (and division) to get the days of the time span…

I could…

What have you tried so far?

What don't you understand from the LabVIEW help for ScanFromString?

Have you tried to subtract two timestamps so far?

(Why do you need a 2nd account now?)
