Time diff using XLSForm

Support
1

Hello Community,

Is there any way possible to subtract a time field from another time field?
For example something like,

*type name calculation *

time TIME01
time TIME02
calculate TIME_DIFF ${TIME02} - ${TIME01}

I tried this but it doesn't seem working and I am not sure if it is
possible either.

Any help would be appreciated.

Joseph,

I think date subtractions work, but time subtractions don't.

Best bet would be to have the user choose hours from a drop down list
(or have them enter it) and do the subtraction manually.
