As I was checking things, it turns out that we _should_ keep the '@' symbol
if only to make sure that our new schedule overwrites the old schedule.

The alternative is that we manually try to delete the old schedule, but that
feels like an inefficient way to do it, leaving some cruft around long-term.

For completeness, here is what I did to check:

$ systemctl --user list-timers
NEXT                        LEFT        LAST                        PASSED       UNIT                         ACTIVATES

Do you have an alternative idea how to handle that?
