Time and Date Settings

So I just noticed my time setting was set to manual. I went to change it to automatic and got an error message indicating NTP is not installed. So looking for NTP installation instructions in 18.04 I came across this article which says “Ubuntu's default install now uses timesyncd instead of ntpd” My clock seems to be correct, so I assume my time is automatically updated even though the system says it is manually updated. Just curious why auto update is not indicated, if there is any other information about this topic and if NTP is recommended for any reason?
