	help

	  Print epoch values when device enter and exit out of suspend

	  and resume. These epoch values are useful to know how long

	  the device is in suspend state. These values can be used to

	  synchronize various subsystem timestamps and have an unique

	  timestamp to correlate between various subsystems.
