Actually using %^<>T as format string container as mentioned by ogk.nz treats the string directly as UTC. However I found something else on my computer which sounds strange. I had to remove the %p format specifier and instead use the 24 hour clock here, in order for the Scan from String function not to return with error 1 (argument error). Also using %p in a Format to String function produces an empty string.
And for some reasons I seem not to be able to change the data and time format from the HH:mm:ss on my Windows 10 system. Maybe it's one of the settings our company feels should not be changed, after all who the heck still uses this pretty confusing AM/PM clock anymore?
But even changing the country setting from Netherlands to United States didn't seem to allow LabVIEW to use the %p format specifier on my computer. So definitely something else to consider for people who need their application to run in more countries than just their own.
