The timer stop at 3:40 was actually when they scrubbed the 3rd attempt on Monday. It's just that nobody reset the clock. Although SpaceX definitely seems to prefer a running clock most of the time, when they do stop it goes back to whenever they need it to go back to. I've seen 18 and 16 minutes in a couple of the 3 holds they've applied so far (not counting the two scrubs).

FYI, per the webcast page, they're taking a look at the engines, and it could be a few days. Not my department, so I know nothing. I'm sure it'll be announced when the launch crew goes for it again.
