I wouldn't have thought so either and given that they all trace back
to GPS it isn't likely either but it made me consider the natioanal
security / financial implications of setting your national clock 10ms
ahead of where everyone else thinks it is.
Chris.
I suspect they all trace back to their own atomic clocks, which gives a
good frequency reference, and then they adjust the phase to all be in
sync. These days I would guess that GPS is used for the phase (time)
sync. There are others on this list who know far more about this than I
do, though.
So if your loan is 10ms overdue, how much extra interest might you get?

I was thinking more along the lines of a stock market open times /
trade times.
Chris.
ISTR that the stock markets require time stamps to be within two seconds
of the "true time". That's not terribly demanding, given the available
technology.
