Time & Attendance par Artholl

Basic time tracking of your work hours. You can fill hours and minutes with or without colon, add breaks, fill shift duration and the extension will show you how long you already worked today, how long you still have to work to the end of the shift and expected end of your shift if you don't take any other break.
There is also support for the Workday autofill. If you go to the calendar and open day you want to fill, you can press Fill button and it should add times from that line to corresponding textboxes in the Workday popup.
