This function rounds a given time to a given duration, taking advantage of the fact that FMP stores times as an integer number (seconds). [Note: Though not strictly necessary, it is likely that the desired calculation result would be of type time.]

The 'up' parameter, which dictates rounding direction, should be either 1/true (up) or 0/false (down).

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


if you want to round up to 5 Minutes : RoundTime ( time ; 300 ; 1 )
and time is 00:05:00 you will get 10 minutes.
I think the right time should be 5 Minutes.

The improved formula is:

( Int ( (time-up) / duration ) + up ) * duration

UPDATE: And to get 0 Minutes for the time "00:00:00"

The improved formula is:
If (t_time = 0;0; ( Int ( (time-up) / duration ) + up ) * duration)
