GPS SA and Network Timing

During the recent attacks, there was a brief discussion as to whether the
USG had or would invoke GPS SA.  We have a client who is building a broad
ATM network and had planned to use GPS based timing solutions from TrueTime
for a clocking source, in addition to a feed from the LEC.

If GPS SA is invoked down the road during a crisis, what effect is there, if
any, on networks which rely on GPS for timing, not positioning?

"It is so easy to miss pretty trivial solutions to problems deemed
complicated.  The goal of a scientist is to find an interesting problem,
and live off it for a while.  The goal of an engineer is to evade
interesting problems :)"  -- Vadim Antonov <avg () kotovnik com> on NANOG
