void hw_GetSysTime(struct hwos_TimeVal *tv);
struct hwos_TimeValyou pass to this function. The system time is counted from a platform-dependent start time defined as 0 and is monotonically increasing. You can use the related functions hw_SubTime(), hw_AddTime(), and hw_CmpTime() to work with the time stamps returned by this function.
struct hwos_TimeValto hold the current system time
