So does ntpd.  I think chrony may also monitor the time of year clock to 
allow it to correct for when the machine, rather than just the network 
is down.

Note that ntpd only saves the clock frequency every hour, and I am 
becoming quite sympathetic to the idea that chrony behaves better than 
ntpd in real world conditions.
