  • Patent number: 8838486
    Abstract: For reporting, recording, and/or employee timekeeping, an exemplary time manager interface on a display of a communications device allows an employee to track his or her work time and activities. The time manager interface connects the employee to a central time manager system that tracks and records employee check-in and check-out times. The time manager interface may also permit employees to view their and other schedules. The time manager interface is able to compensate for the time spent initially connecting to the network and launching the interface by recording the network logon time as the check-in time when the difference between the network logon time and the actual reported time is below a predetermined threshold.
