Ron,

What Internet connection do you have?  I see delays of 25 - 35 ms on my 
cable modem connection, which is 30 Mb/s down and 1 Mb/s up.  I don't know 
whether delays of 54 - 84 ms are what would be expected on your 
connection, but they seem long delays to me.  It may be worth checking 
whether your ISP has an NTP server.  Sometime stratum-1 NTP servers can 
get overloaded because too many people connect to them, and stratum-2 
servers will give better results (especially if they are better connected 
to you).

Cheers,
David
