Momentarily donning my tinfoil hat here, as I certainly don’t claim to
know the nitty gritty of how GPS timing works, but…

What if, since the GPS system is operated by the US Air Force, there was
something slipped into the GPS system relating to timing or accuracy or
similar due to the events in the tinderbox of the Middle East?
