For dive computers where the reference time (epoch) of the device is unknown, libdivecomputer uses the current time of the device (devtime) and the host system (systime) to synchronize both clocks. Currently, both timestamps are passed directly to the constructor of the parser. With the new public function, the application can adjust the timestamps afterwards.
