Title is probably not helpful.
What I observed and cannot understand is:
Yesterday I copied data from the log to excel
Today I copied the same data from the log and the time stamp is different.
See yellow below
Now I doubt the 6 milliseconds will matter to my data 
but I do find the difference odd.
Perhaps it is converted each time the logs are accessed and the conversion has some variability?
Hmm... Could be caused by clock drift...
I'm assuming a log entry is a piece of data stored somewhere in the hub. To drift with the clock the data would have to be somehow related to the clock each time the logs are loaded. I don't see how that can happen in logged data.
Fair enough... Thinking about it more a process could have been running at the same time and the log entry was delayed by milliseconds.
There is hub time -> browser time translation involved using Moment JavaScript library. This is most likely an artifact of that translation.
