Differences between working hours, timecard stamps and timesheets

Working hours

Working hours are linked to a human resource and define what are the work days of the week and the ammount of hours they are supposed to work in those days. Working hours can be only created by users with the Human resources admin role. Working hours allow you to calculate:

  • The hours not stamped in the timesheets reports (calculated by subtracting the stamped hours from the total contract hours);
  • The hours balance in the timesheet report (calculated by subtracting the hours entered in the timesheets from the hours in the contract);

Timecard stamps

Timecard stamps are time strings linked to a workplace, they can be either clock-in or clock-out type. When both a clock-in and clock-out type timecard stamps are registered in the system an attendance type event can be automatically created in Timesheets. This attendance will by default be locked (not editable). This way timecard stamps allow monitoring of actual attendances and absences of collaborators during working hours. In RevasOS attendances cannot be longer than thirteen hours, complying with EU regulations.


A timesheet is a collection of time entries manually generated by the collaborators to record a work hours period. A timeesheet time entry has a description, both a start and end time and date. Optionally it can have a linked workplace or absence type and a linked task. If configured timecard stamps can automatically generate a corresponding timesheet time entry. Timesheets allow monitoring both attendances and absences of collaborators. They also allow for advanced and simple reporting in projects and tasks.
