Abstract

This disclosure relates to systems and methods for functionality-specific system time synchronization. In one embodiment, a method is disclosed, which comprises determining whether functionality-specific system time information is available from a first server. If the functionality-specific system time information is available from the first server, a first request for functionality-specific system time information is transmitted to the first server. A first functionality-specific system time is received from the first server. A second functionality-specific system time can then be generated based on the first functionality-specific system time. If the functionality-specific system time information is not available from the first server, after a second request for functionality-specific system time information is received from a second device, the method further comprises determining whether to provide a local functionality-specific system time to the second device.
