What do you mean by that? starting the timer doesn't mean you start
the service that the timer is supposed to start eventually, it just
means you start the timer, that's all.

If you don't to add a timer without starting it, just place the unit
file in /etc/systemd/system, and issue "systemctl daemon-reload",
without "systemctl start foobar.timer"...

What do you mean by "run immediately"? Are you saying the service the
timer is supposed to start is run immediately (which would be a bug),
or just that the timer is now "hot" and waiting till its time arrives
(which is exactly what starting a timer means).

Anyway, confused what you are trying to say...
