Thanks, it's good to know there are dictionaries out there with
incorrect definitions. That one is terrible and unhelpful.

Please use the standard definition of “time zone”, otherwise your
terminology is only got to confuse the conversation.

This just doesn't match the truth of standard time zones. You are free
to think differently, but you will need to find a non-standard time zone
database that agrees with you.

> you are totally wrong ,not me .

You're free to keep on with that belief, but I'll only be providing
information based on standard time zone definitions. If you choose to
deviate from that, you're on your own.
