CLDR is able to support names used for pre 1990 dates only technically.
If CLDR project really wants to handle the distinction between "Irish Summer Time"
and "Irish Standard Time", it's doable.

However, CLDR technical committee does not want to take an effort to localize
zone names never used in last 30 years for hundreds of locales. It's just a policy
issue.
