timestamp in 4.8?

[Richard P. Williamson]

Is there a reasonable timestamp (that uses a struct timeval
to return data by preference) in 4.8R?

TSTMP (option KERN_TIMESTAMP) writes the rdtsc clock
value to debug.timestamps in sysctl-space.  That does
not suit my purposes (need to timestamp the creation
of objects which are passed about).

TIA,
