Function 
Description 
Gets the current system time. 
Gets the time since the epoch in second.(00:00:00 UTC, January 1, 1970) 
Sets the system time. 
Gets the count from the microsecond timer (ust), a hardware timer. This microsecond timer counts the microseconds passed from the time the system is powered on until now. It allows the caller to measure the durations in high precision. To calculate the duration between different timer counts, use vm_time_ust_get_duration(), instead of simply subtract values, because the timer counts may wrap around. 
Gets the duration from start_count to end_count, in microsecond. The caller should ensure that the end_count is equal or greater than the start_count.
