[erlang-questions] erlang time in vmware

[Fredrik Thulin]

Hi

I was just bit by a strange problem - I have an Erlang node running on a 
VMware ESX 3 guest operating system (Linux 2.6) with VMware tools installed.

Apparently, vmware tools makes sure the system clock is correct, even 
though the guests CPU frequency varies greatly based on actual need. 
This is why NTP is not used.

My Erlang VM however, ended up ~270 seconds into the future after 
running for about a week. The system time as reported by 'date' showed 
correct time. Can someone explain this, and hopefully also tell me how 
to avoid it in the future?

Thanks
