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.

These are my opinions.  I hate spam.
