I have applied the following formula to get the above result for DateTime Difference
datediff('minute',[Start Time],[End Time])
Why it is giving me wrong value?
This possibly might be the result of aggregation.
You could check by turning Analysis > Aggregate Measures off.
If your DateDiff pill is currently set to SUM, you could try
MIN or MAX or AVG to possibly get back to 60 min.
