20 minutes on a real timesheet
Twenty minutes is the classic "third of an hour" entry: 0.33 on a two-decimal timesheet, 0.3333 unrounded. It is also one of the values most affected by rounding rules — under the common 7-minute rule, a 20-minute block rounds down to 15 minutes (0.25), so the same shift can log as 0.25 or 0.33 depending on your employer's system. If you track your own hours, write 0.33 and let payroll apply its own rounding.
