Notes from the time database
The story behind the clock
These source notes describe a period or rule. They do not, by themselves, establish a causal claim for a particular clock change.

Decree No. 142 (1917-12-22)
Older C-Eur rules are for convenience in the tables. From 1977 on, C-Eur differs from EU only in that C-Eur uses standard time.
The following rules are for the European Union and for its predecessor organization, the European Communities. For brevity they are called "EU rules" elsewhere in this file.
