I've been seeing errors like the following appearing:

Jun 30 03:13:57 ford kernel: calcru: runtime went backwards from 261
usec to 258 usec for pid 516 (devd)
Jun 30 03:13:57 ford kernel: calcru: runtime went backwards from 4976
usec to 4926 usec for pid 367 (pflogd)
Jun 30 03:13:57 ford kernel: calcru: runtime went backwards from 588
usec to 582 usec for pid 133 (adjkerntz)
Jun 30 03:13:57 ford kernel: calcru: runtime went backwards from 681
usec to 674 usec for pid 20 (swi6: task queue)
Jun 30 03:13:57 ford kernel: calcru: runtime went backwards from 486
usec to 481 usec for pid 0 (swapper)

and narrowed down the cause to openntpd.

Do these errors fall into the Mostly Harmless category?
