So they'll eventually agree on a time more or less in the middle? One would
eventually jump ahead (in 2 minute increments max) and the other would jump
back 30 minutes or so?

With peers, nobody has authoritative time. That means, you might think it's
1pm and I may think it's 2pm, but we have no idea who is right so BOTH of us
will adjust our time (max of 2 minutes each jump) until we finally
compromise.

With client/server, the server actually has the authority, so clients will
jump their time no matter how far off it is.

Hello, I went through the documentation to identify what is the difference
between NTP server and NTP peer statements. The only difference I could
find is that ntp peer allows both hosts to sync with each others while ntp
server
allows the host only to sync with the time server. THe question is when
should i use the peer and when should I use the server when the question
specifies to sync with BB1? Thanks for the calrification, Regards,
