Ok, so here is my analyses done with a KT03 and Eth03. I had Bus Monitor capture the data and then made a manual change to Comfort to see the outcome. I must say that I do NOT get the eventlog entries every 10mins like some of the other users and that I checked my RTC to be within 1s of NTP time over a 24H period.

Bus Monitor Log:

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

Set time here to <NTP> minus 3s to see if the Eth03 will correct it. Restarted Bus Monitor again.

19: 03: 21: 457 ----< 03 14 53 32 30 31 35 30 39 31 30 31 39 30 33 31 36 30 30 31 36 02 <--->S201509101903160016 Time changed here by Eth03
19: 03: 21: 473 ----< 03 00 53 32 30 31 35 30 39 31 30 31 39 30 33 31 36 30 30 32 41 02 <--->S20150910190316002A and Broadcast to all.

Wait for next update @ ~19:13:17... Checked time and is 100% correct.

19: 14: 02: 917 ----< 03 14 53 32 30 31 35 30 39 31 30 31 39 31 33 31 37 30 30 30 35 02 <--->S201509101913170005
19: 25: 19: 686 ----< 03 14 53 32 30 31 35 30 39 31 30 31 39 32 33 31 37 30 30 46 35 02 <--->S2015091019231700F5 

EventLog entries:

Changes shown below where I made the manual DT change and where the Eth03 updated the time to the correct NTP time. No other entries appear whatsoever.

09/10 19:01 Date/Time Change 66 <- KT03
09/10 19:03 Date/Time Change 20 <- Eth03

If someone that get eventlog updates every 10 minutes do the same Cytech can compare the data and perhaps find a way to correct it. Just a quick PS. 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, I might try the same test later with 2s time difference.
