Recommended NTP application

[Eric Gammeter]

What Network Time application to use?  I have a Raspberry PI4 and WEEWX 5.2.

I have been happy with chrony(d) thru the years. But others may have suggestions.

Imo, it is lighter weight and has better ntp server selection than Dr. Mill’s ntp implementation (which is the gold standard)

Presumably you mean an NTP client. One is already bundled in Raspberry
Pi OS--systemd-timesyncd. You can see if it's running by running:

sudo systemctl status systemd-timesyncd.service

If it shows that it is not running then start it with:

sudo systemctl start systemd-timesyncd.service

Then to ensure that it is started on every system restart enable with:

sudo systemctl enable systemd-timesyncd.service

Check its status again to see that it is running and enabled.

That is all there is to it, no additional packages to install and
configure.

If you have a time server on your network, then it can be added by
editing /etc/systemd/timesyncd.conf, uncommenting the "NTP" line and
adding its IP address or host name.

You'll likely never have to mess with it again.

I install ntpsec which works far better than the thing built into systemd. Works much better for catchup to true time on initial startup and big feature is it is not the systemd borg.
