Might or might not be. At least for GPS and Galileo there is an agreement
to synchronize the clocks and have a field in the message data that specifies
the difference between UTC(GPS) and UTC(Galileo).
There was some discussion at last EFTF about how they are going to measure
the time difference accurately. Apparently the GPS people were not impressed
by Galileos plan to have a physical realization of UTC(Galileo). They seem to
have run into problems in the past and have thus switched to a paper clock.
I pity people who can't find laughter or at least some bit of amusement in
the little doings of the day. I believe I could find something ridiculous
even in the saddest moment, if necessary. It has nothing to do with being
superficial. It's a matter of joy in life.
