It's probably worth mentioning that you are assuming buffer bloat and friends
are not causing troubles.
I have a 384 DSL line. I regularly see queueing delays of over 3 seconds. I
don't remember ever seeing offsets of over a second, but many hundreds of ms
are common. It wouldn't surprise me if somebody had a slower link that would
kick the offset over 1 second.
