Maybe its power saving related.  Timing is not stellar on mac in general.

Out of curiosity I checked my FreeSWITCH logs and since April 6 there
have been 66 occurrences of the Reverse Clock Skew Detected message and
22 of Forward Clock Skew Detected.

Detected!
2014-07-31 11:24:21.023302 [CRIT] switch_time.c:1104 If you see this
message many times consider a nicer machine to run me on. I AM *FREE*
after all.

The machine is a 2.3GHz i7 Mac mini with 8GB RAM running 10.9.4 and is
basically 95-99% idle. The only thing it's running is FreeSWITCH for
home--two extensions and two DIDs. There's no pattern I can see when the
skew messages occur. Usually once every 1-3 days, but infrequently it
can be 2-3 times per day. Monotonic clock issue? Anything to do about
it?
