kern_timestamp - return (machine-dependent) timestamp
SYNOPSIS
#include <sys/time_stamp.h>
kern_return_t kern_timestamp(struct tsval *tsp)
ARGUMENTS

pointer to a struct tsval to receive the timestamp.
DESCRIPTION
kern_timestamp()

DIAGNOSTICS
- KERN_SUCCESS
-
The timestamp has been returned.
- KERN_INVALID_ADDRESS

Availability limited. Timestamp format is machine-dependent;
the value
of the symbol

Multimax timestamps are subject to rollover on
an hourly basis (2^32 usec). Timestamps on most other systems have a
granularity of 10ms.
