I'm curious as how this disruption could be used in a financial scenario. If you disrupt the GPS for 10 minutes, would the timestamps really go that out of whack?
And more importantly, will they go out of whack in a way that's useful? Being able to shift the timestamps a few microseconds could be quite valuable if you can do it only to your order gateways (and ensure it's in the correct direction) but "jamming GPS" doesn't seem to get you that. I'm not going to say there's nothing it could be used for, but it's not jumping out at me.

They shouldn't, of course (not over a period of time as small as 10 minutes).
Remember, though, that the time a trade occurred (at the sub-millisecond level) might well mean thousands of dollars (or more).
