Time difference

[willcan]

Hello all , 

Two Different time values in string format to be subtracted. Result to be displayed as a string

time 3 = time 2 - time 1

need your guidance and tips

Can you be specific what is your time format in string ? e.g 10:43:16

Essentially you will use Scan From String to convert your time strings to Timestamps, then subtract the values (you may need to convert to DBL first), then you can format the resulting DBL value to a string using Format Into String. The LabVIEW help has info on the format codes for Timestamps:

Your minutes are actually show the number of seconds after the hour.  You need another Quotient & Remainder to divide by 60.

OR

You can eliminate a lot of that code by just using the Format Date/Time String.

When I come across a solution to something, I try to make it generic.

Drop the .xnode file onto your BD.

Right-click (or click with the Operate tool) and you can change the mode and the string format.
