IF function: Perform a simple logical test depending on the comparison result, and it returns one value if a result is TRUE, or another value if result is FALSE.

As if the difference between two times is a negative value, Excel will display it as #####. For avoiding this, we use IF function. Supposing time2 is larger than time1, then it displays the result as time2 -time1, if does not match this condition, it shows the result as time1-time2.


This formula cannot handle durations greater than 24 hours.
