The number of hours worked by non-exempt employees are calculated using the quarter-hour rounding method. This means that an employee’s arrival and departure times are rounded to the closest quarter of the hour when calculating the timesheet. Using 8:00 AM as an example, employees will be paid from 8:00, 8:15, 8:30, 8:45 or 9:00.

This is my Custom Function and I want to edit it


I don't think this works.

Anyway, to round a timestamp to the nearest quarter hour, you only need to do:

Round ( timestamp / 900 ; 0 ) * 900

Thanks for your comment Mr. VM
I think you meant:
GetAsTime ( Round ( Get ( CurrentTime ) / 900 ; 0 ) * 900 )

because Timestamp function has 2 parameters date and time
Timestamp ( date ; time )
