Do you need wall clock time, or do you just need relative timestamps
to other dtrace prints?  timestamp works in all FreeBSD versions and
you can print it as a simple int.  The counter is given in nanoseconds
(I believe that it's specifically the number of nanoseconds since
boot, but don't quote me on that).

Alternatively, the code to implement walltimestamp was quite simple,
so you could investigate back-porting that:
