Does Default Ubuntu use ntpd or timesyncd?

Question

In the question linked, I ask how I can get time syncing to work. Why is the time not syncing?

The answer given was to check my NTP configuration. Why would I do that? I thought Ubuntu switched from ntp to timesyncd when systemd was adopted. What is the Default time syncing method on Ubuntu?

Ubuntu 18.04

Answer 1

Default Ubuntu uses timesyncd, and this has been the case since Ubuntu 15.04 (April 2015)
