In the chrony.conf included in this package:

Chrony has been configured on the assumption that you are using either a dialup
connection or a PPPoE DSL connection.  It will be brought online when PPP 
comes up and offline when it goes down.  If this is not correct you should edit
/etc/chrony/chrony.conf.  The comments explain what to do.  For more 
information on configuring Chrony use the command  'info chrony'.

You can also change the default time servers in  /etc/chrony/chrony.conf.

Updating of the real-time clock has been enabled but some systems that use
either the genrtc driver or have HPET hardware clocks have problems.  To
disable real-time clock updating edit /etc/chrony/chrony.conf.  The
comments explain what to do.
