Comodo AV Update clock v My PC Clock?.

Since installing v5 last Thursday apart from a minor problem with my cursor which I have posted in the Bugs section it has run faster, smoother and more seemless than any Comodo since v2.5 in my opinion. I just noticed though this morning that there is in general between 20 and 30 minutes of difference in the time that my AV updates itself on the Comodo GUI and the actual time of my PC. Now I have checked and the PC time is correct for here in the UK. This post will show the same time as my PC on the header when I post it just now so it is not a settings related problem. Is there a reason for this time differential in the AV updates as it was always the same time as my PC in previous versions?.
