How to calculate Hours and minutes using Business Hours?

Question

I have used this to calculate hours , but minutes part is not getting covered.

long businessMillisecondsDiff = BusinessHours.diff(bh.Id,cs.CreatedDate,system.now());
decimal businessHoursDiff = businessMillisecondsDiff / (1000.0*60.0*60.0); 

Answer 1

It does give you both, you just get minutes as a fraction of hours. If you want minutes only, you can just divide by 60:

Decimal businessMinutesDiff = calculatedDiff / (1000*60);

Or, if you want whole hours and the number of remainder minutes:

Decimal businessMinutesDiff = calculatedDiff / (1000*60);
Decimal hours = businessHours.divide(60).round(RoundingMode.DOWN);
Decimal minutes = businessMinutesDiff - 60 * hours;
