I *think* it reports RemoteWallClockTime (or perhaps
CumulativeSlotTime, which is the same value if you're not using slot
weights). So in your example it would report 4 hours.

In this case the RUN_TIME parameter is muddled up, for which I guess HTCondor has no blame.....but it also means that in this setup the RUN_TIME parameter should not be used for accounting and/or billing users....

It depends on what you want to accomplish. If you only want to bill
them for the successful runs, then you can use CommittedSlotTime. If
they get charged for badput, too, well, then the sudden disappearance
of a machine is a risk they take. I'm sure you can shorten the time it
takes the schedd to realize the startd has disappeared, but I don't
remember the exact settings offhand.
