    Increased Adoption of GPS Time: In addition to position information, the
accuracy of the time data broadcast by GPS will
    improve to within 40 billionths of a second. This improved level of
precision may encourage continued adoption of GPS as
    a preferred means of acquiring Universal Coordinated Time (UTC) and for
synchronizing everything from electrical power
    grids and cellular phone towers to telecommunications networks and the
Internet. For example, with higher precision
    timing, a company can stream more data through a fiber optic cable by
tightening the space between data packets. Using
    GPS to accomplish this is far less costly than maintaining private atomic
clock equipment.

I wonder just how much consideration this was given as an effort to reinforce
GMT over PMT?  I guess we'll be able to judge that somewaht by news coming from
Paris over the next few days.

Nope.  Accuracy yesterday was 100 meters, today it's 10 meters, according
to what I've read:

Hope this helps.

The most exciting phrase to hear in science, the one that heralds new
discoveries, is not "Eureka!" (I found it!) but "That's funny ..."
