It seems really unlikely that all of your channels are off by the same 
amount.  Have you used ntpq to verify that the time is really being set 
with NTP?  Try "ntpq -p".  Look for and entry with an "*" beside it.  
Look at the "offset" column in this row.  This is how many ms your clock 
is off.  You should normally see something less than 100.
