No EU law specifies how a time tracking system should round work hours. Each provider decides for themselves, so the rules below are specific to TwoWork.
When an employee clocks in and out, we measure the exact time between the two, down to the second. We then round that one registration to the nearest whole minute: 29 seconds or less rounds down, 30 seconds or more rounds up.
Example: an employee clocks in at 08:00:00 and out at 15:32:40. The exact time worked is 7 hours, 32 minutes and 40 seconds — the 40 seconds round up, so the registration is saved as 7 hours and 33 minutes.
The daily, weekly, and monthly totals — and the Excel export — are the sum of those rounded registrations. The number an employee sees in the app right after clocking out is the exact same number that ends up in your export.
The decimal hours in the export (e.g. 7:33 shown as 7,55) are calculated from the hours and minutes and rounded to two decimals.
Because it evens out. Some registrations round up, some round down, and across a full payroll period the rounding favors neither the employee nor the employer.
