=2E..if your system has clock_gettime.
You may or may not need -lrt.

To test:

$ echo hi|tai64n|tai64nlocal
2007-08-29 19:57:27.380816809 hi

To (hopefully) restart multilogs:
# kill $(lsof -c multilog -t)
or if you use supervise:
# svc -t /service/*/log

--=20
Do what you love because life is too short for anything else.
