During the discussions on whether we should be using time zone or if timezone was acceptable, a few interesting miss uses of timezone came to light.

XML Schema Part 2: Datatypes Second Edition

3.2.7.3 Timezones defines as a fixed minute accurate offset with no provision to identify the daylight saving element.

Python

datetime.timezone also defines timezone as a fixed offset
The timezone class is a subclass of tzinfo, each instance of which represents a timezone defined by a fixed offset from UTC. Note that objects of this class cannot be used to represent timezone information in the locations where different offsets are used in different days of the year or where historical changes have been made to civil time.
