This service call updates the system time.
The isig_tim is automatically started every tick_time interval(ms) if the system clock is defined by the configuration file.
The application cannot call this function because it is not implementing as service call.
When a time tick is supplied, the kernel is processed as follows:
(1) Updates the system time
(2) Starts an alarm handler
(3) Starts a cyclic handler
(4) Processes the timeout processing of the task put on WAITING state by service call with timeout such
as tslp_tsk.
