Absolutely. AttendanceBot can remind you to punch in or punch out in case you forgot to do so during office working hours and are not on leave on that day.  You can specify the time for both punch in and punch out reminder. This reminder would go to all members of the slack team at their respective local time.

Here is what a punch in reminder looks like.

To enable this go to your settings panel by typing 'settings' and scroll down to the Time tracking settings section.

You can also choose to automatically punch out people (as opposed to simply reminding them of it) by enabling and setting an "Auto Punch Out" time.
