Was this change supposed to change the transition time on May 23, 1955 
as well? 

For PHP I'm seeing a test case fail as it tested for the transition to 
happen at 1955-05-22 23:00 UTC / 1955-05-23 01:00 CET

The 2020b NEWS item only mentions: "Correct several transitions for 
Hunggary for 1918/1983. For example, the 1983-09-25 fallback was at 
01:00, not 03:00" and makes no mention of the May transition times, or
