Hello everyone,
I have a Nintex form with the following fields:

In Prior Date & Time Relieved: the first control is the standard datepicker and the remaining two are choice controls for hours (0-23) and minutes (0-59). The same thing applies for Date & Time: Time on Duty.
Is there a way I can concatenate the date, hours and minutes values for both the highlighted fields to represent a date with hours and minutes (for eg: 07/16/2019 03:49)? If yes, can I subtract these values to show the difference in hours and minutes? The requirement is to subtract Prior Date & Time Relieved from Date & Time: Time on Duty as follows:
if Prior Date & Time = 07/16/2019 15:00 and Date & Time: Time on Duty = 07/16/2019 16:00, the calculated value should show 01:00.
I know we can subtract dates using 'datediffHours' and 'datediffMinutes' inline functions with the standard datetime picker control, but it only supports 5 minutes increments and I need 1 minute time increment.
Please let me know if this could be done.
Thanks,
Adi
