[Freeswitch-users] Clock Skew

[Peder @ NetworkOblivion]

Any idea what this means:

2008-05-05 09:01:44 [CRIT] switch_time.c:351 softtimer_runtime() Forward 
Clock Skew Detected!

It is a test box that I installed with RC3 and don't have anything on it 
right now.  The clock appears to have the correct time.  I know what 
skew means, but what does it mean in terms of freeswitch?  What is it 
skewing from?
