Yes:  "peer synchronization loop"

I tend to use Google, which for "ntpq" brings up:


Unfortunately, that page doesn't have any explanation of the codes, indeed 
the section "peers" is confusing to me in that the columns are listed as:

ind assid status conf reach auth condition last_event cnt

which doesn't seem to agree with the output I see, for example:

C:\>ntpq -p
     remote           refid      st t when poll reach   delay   offset 
*feenix          .GPS.            1 u  246  512  377    1.109   -0.261 

or the table below in the document.  It's in the table below where the 
meaning of the letters could be added.
