I need to set the date to several years in the future in order to test something.  When I do this via the date command, the date returns back almost instantly (or within a few seconds).

I’m not using ntp (that I know of).

# timedatectl timesync-status

Failed to query server: The name org.freedesktop.timesync1 was not provided by any .service files

# timedatectl show

How can I stop (temporarily) the system from automatically setting the date so that I can set it forward?

I encountered this type of thing myself a while ago as well. And, just like you, I thought there was no NTP running, but systemd had some tricks upon its sleeve.

Try this to see if it solves your troubles:

# timedatectl set-ntp true

Changes to the status of this service will not be immediately noticed by timedatectl. Thus, you'll have to enter the following command too:

# systemctl restart systemd-timedated.service
