Re: [ldm-users] dvb1.ssec clock problems??`

Don't know if it's relevant but we've had issues with significant
VM-Server time drifting which ntp doesn't seem to play nice with. It
sounds similar to the original description where ntpd is running but not
keeping the time in sync. 

I believe we've limited the issue to ESXi based hosts but I'd have to
double check that. Note that's ESXi, not pure ESX. We've just abandoned
those hosts from any time sensitive uses since the issue hasn't been
addressed and we have other options for virtual hosts.
