Thanks for all your fast replies. Glad to hear there is nothing to worry about.

What I did want to know is which website would be more correct? UA .bomb or the flightstats?

It seems strange that flightstats appears to be more up to date than UA for their own flights .

And yes, it may only be 10 mins, its not the time per se, its the stories I have heard on FT saying that a simple 1 min schedule change can throw all the seat assignments out. I am on the UD for the very first time with my child, as I am not going to be awake (its midnight here) to see if or when UA catches up and reflects the schedule change (if it does exist), I was trying to get a picture of how real this schedule change might be and how likely it is to affect my well selected seat assignment

Furthermore, the UD is basically full except for 2 single seats at the front, and the rest of C class is pretty full also - with all the good seats taken, so I was trying to use the FT knowledge to ascertain whether this is or is not going to be an issue. Hope that clarifies it further.
