[ntp:hackers] What happened to old sample checking?

Some time ago, Dave added a check in clock_update such that is the 
sample being used to update the clock was older than the last sample 
used to update the clock, the older sample would be ignored. This 
ensured that the samples applied to the clock would be in 
chronological order.

Looking at clock_update recently, I see that this check is no longer 
in place. It was there in p161 and is not there in p167.

So, I guess this is really a question for Dave. What happened? Was the 
check moved somewhere else, or did you decide that it wasn't working 
right, or that it was not the right thing to do?  I am just trying to 
understand what happened.
