Tell them to stop doing so.

And explain to them that the name of a tzdb zone is *N*O*T* an authoritative source for the name to be used for the city that happens to be used for the zone name.  Tell them to read

	https://data.iana.org/time-zones/theory.html#naming

very carefully, and if they still refer to the tz database after reading that, tell them to read it *again*, as they clearly didn't understand what they were reading.
