That isn't the contrast in ISO 8601. It says:
2.1.16 local time
locally applicable time of day such as standard time of day, or a
non-UTC based time of day
The relevant distinction is from the late 1800s, between local mean solar
time and time based on a standard meridian, as in railway time. So ISO
8601 is right that summer time is also a standard time (in this sense)
even though the North American terminology that distinguishes between
(original) standard time and daylight saving time is clearer.
