"Works as designed":
A process inherits time zone information when it starts, from the par=
ent
and the then valid environment.
This also holds for the MySQL server.

That is why time zone information contains the info about when daylig=
ht
saving time starts / ends:
A process starting before the change and still running after that wil=
l
use the correct time only because it got the information (about the
change point) already when it started.


HTH,
Jörg
