I see only repeated made-up arguments to add an exotic feature, which
I don't see adding any real value.
DST for the machine is "presentation only". Tools handling it turn the
"presentation" into the actual machine's time and be done with it.
Glibc does that for us today already and it already works sufficiently
for systemd's calendar time support.
If the system's time zone changes, or the time is adjusted manually,
we just re-arm all timers, and all should be fine.
I see no need or use to support explicit triggers on the event of DST
changes, the system or calendar time support just does not need them.

I'm not willing to discuss things in that tone.
