samba - Jul 2017 - samba domain member server: ntp via chrony

I found

https://wiki.samba.org/index.php/Time_Synchronisation#Set_up_the_ntpd.conf_File_on_a_Unix_Domain_Member

with ntpd.conf

Does anyone use chrony(d) instead and can provide a working config file?

I know how to add a server there, sure, but I wonder if there are any 
specific options or parameters that make sense in this context.
