NAME
       kern_timestamp  -  return (machine-dependent) timestamp

SYNOPSIS
       #include <sys/time_stamp.h>

       kern_return_t kern_timestamp(struct tsval *tsp)

ARGUMENTS
       tsp	      pointer to a struct tsval to receive the timestamp.

DESCRIPTION
       kern_timestamp()	 obtains  a  current  low-overhead  timestamp from the
       kernel.

DIAGNOSTICS
       KERN_SUCCESS		The timestamp has been returned.

       KERN_INVALID_ADDRESS	tsp doesn't point to valid user memory.

BUGS
       Availability limited.  Timestamp format is machine-dependent; the value
       of the symbol TS_FORMAT must be saved for convert_ts_to_tv().  Multimax
       timestamps are subject to rollover on  an  hourly  basis	 (2^32	usec).
       Timestamps on most other systems have a granularity of 10ms.
