As your expression meant to show always no of minutes from Month Start till now why not to use this expressions:
or if you like to format it nicely i would use interval function like this:
=Interval(Now()-MonthStart(Now()),'ddd hh:mm:ss') which will result in somtehing like this: 013 10:55:53
=Interval(Now()-MonthStart(Now()),'mmmmm:ss') which will result in somtehing like this: 19376:53
Those expressions can be implemented in script, variable calculation or expression field.
