We have upgraded our deficit hours tracking functionality so that you can automatically record deficit hours not only for days with time tracked, but also for days with no time tracked. 

The improved functionality consists of:

• The Track automatic deficit hours for days with no time tracked option available through Settings > Attendance > Working Hours > Overtime & Deficit Hours.
• When active, a deficit hour entry will be automatically generated for every workday in which the employee is supposed to track time but does not.
• The message No time tracked will appear in every workday in the employee's attendance calendar. 
• The overtime hours will be automatically recalculated based on the registered deficit hours.

This feature is integrated into new accounts at the moment and will soon be released for all the users.
