SUB_TOD_TOD

Subtract TIME_OF_DAY from TIME_OF_DAY

SUB_TOD_TOD subtracts a value of the data typeTIME_OF_DAY from another TIME_OF_DAY value. The result is stored in the output variable of the data type TIME.

Parameters

Input

Unnamed input (TIME_OF_DAY): 1st input: minuend
Unnamed input (TIME_OF_DAY): 2nd input: subtrahend

Output

Unnamed output (TIME): Result
