Is there documentation on how to set this up ?

Please, try this:

https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/bbb-releases/bbb-dunfell/local.conf

This is the systemd addendum in my BBB Dunfell local.conf :

## Add systemd service
DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
VIRTUAL-RUNTIME_init_manager = "systemd"
VIRTUAL-RUNTIME_dev_manager = "systemd"
VIRTUAL-RUNTIME_initscripts = ""

With systemd added, you'll inherit timedatectl tool.

Best Regards,
Zoran

Hi Steve,

I currently have "ntpq" building and installing correctly...

Can someone tell me what it takes to get the "timedatectl" command utility built into Yocto kernel image ?

I see it referenced in both :

openembedded-core/meta/recipes-core/systemd/systemd_234.bb: ${bindir}/timedatectl \
poky/meta/recipes-core/systemd/systemd_234.bb: ${bindir}/timedatectl \

It comes with systemd. Use it as your init system and then you'll have the command.
