Tracking time usage on a disconnected client over a period of time

A method of tracking time usage of an application on a computer during a service period, the method comprising:

• recording a start time for the service period of the application, wherein a plurality of service lives of the application occur during the service period, the service period being a preset time period provided by a subscription associated with the application;
• recording time elapsed during each of the service lives based on a number of computer cycles that occurred during each service life;
• recording time elapsed between each of the service lives based on time elapsed between a service life end time and a next service life start time for each of the service lives, the recorded time elapsed between each of the service lives comprising a sleep cycle for the application during which the application is not being executed;
• determining total time depleted from the service period of the application based on total time elapsed during and between each of the service lives;
• and
• adjusting time left in the service period of the application based on the determination.

A system for tracking time usage of an application on a computer during a service period, the system comprising:

• a non-transitory computer-readable storage medium configured to store software modules comprising:
• a start time recording module that records a start time for the service period of the application, wherein a plurality of service lives of the application occur during the service period, the service period being a preset time period provided by a subscription associated with the application;
• a cycle recording module that records time elapsed during each of the service lives based on a number of computer cycles that occurred during each service life;
• a sleep time recording module that records time elapsed between each of the service lives based on time elapsed between a service life end time and a next service life start time for each of the service lives, the recorded time elapsed between each of the service lives comprising a sleep cycle for the application during which the application is not being executed;
• a determination module that determines total time depleted from the service period of the application based on total time elapsed during and between each of the service lives;
• a time adjustment module that adjusts time left in the service period of the application based on the determination;
• a processor configured to execute the software modules stored by the computer-readable storage medium.
