If you're using FreeSWITCH in a virtual environment we've had similar issues when using FreeSWITCH on a Hyper-V VM, the time on the VM seems to run at a slightly difference pace. When the VM syncs with the host FreeSWITCH doesn't pick this up.

We found using sync_clock fixed this which we run daily as a scheduled task which executes the command 'fsctl sync_clock_when_idle' via Event Socket API, also disabled the time sync between the VM and switched to NTP.

It would be useful if FreeSWITCH would execute this command every 24 hours out of the box, I can't think of any circumstances where this behaviour wouldn't be desired.

Subject: [Freeswitch-users] The time on FreeSWITCH is faster than server time

Hey all,

Recently I noticed a clock problem on my FS server, the time in fs_cli had about 10sec faster than server time(correct time), so I executed sync_clock to correct it.
This server had run about 1 month, and I wonder if I need to make sync_clock per month, and how to fix this clock problem.

Regards.
