[Freeswitch-dev] Lag in timestamps reported by FreeSWITCH

I've noticed that if FreeSWITCH (r10423) is left running for several hours (1 day in my case), the timestamps reported in log messages and events sent through mod_event_socket start lagging against the time reported by the server where FreeSWITCH runs. After 1 day, the time in FS was 3 minutes less than the time of the server. We are running ntp on the server, so the time is constantly updated to make sure that it stays correct. What's special about our setup is that all the dialplans are received via mod_xml_curl and that we use mod_event_socket a lot. Has anybody else experienced this problem?
