Thanks for the  results
I am puzzled as to why your time on the left is not the same as the time reported by Comfort
18: 18: 32: 785 ----< 03 14 53 32 30 31 35 30 39 31 30 31 38 31 33 31 32 30 30 30 42 02 <--->S20150910181312000B Set date and time
18:18:32 on your computer vs 18:13:12 from Comfortut 
 I thought the Eth03 would only correct time if its out by 4s or more, perhaps I caught it right on the boundary of 4s
That is not correct. ETH03 will correct the Comfort time as long as it is not the same, but it will not report the time change to the event log if the correction was less than 4 seconds.This way, ETH03 should keep the time accurate but there should be no events in the event log as long as the time correction is less than 4 seconds. If ETH03 does not correct the time if less than 4 seconds then the inaccuracy would  accumulate.
So if the update interval is shorter than the interval at which the clock inaccuracy is 4 seconds then there should be no events
One way of fixing the event log issue is to not update the event log if the correction is less than 1 minute
