Time in Caudonia
Time in Caudonia is de facto divided into two standard time zones: Eastern Standard Time (EST; UTC-05:00), sometimes referred to as Caudonian Standard Time or American Time, as it is used in the parts of Caudonia located within the United States, and Central European Time (CET; UTC+01:00), sometimes referred to as European Time as it is used in the parts of Caudonia located on the European mainland. A third standard time zone, Greenwich Mean Time (GMT: UTC+00:00), was used in the parts of Caudonia located in the United Kingdom during Caudonia's claim.
Daylight saving / summer time
During summer, daylight saving time is observed and all clocks move one hour forward. In all of Caudonia, with the exception of the parts of Caudonia located on the European mainland, Eastern Daylight Time (EDT; UTC-04:00), is observed between the second Sunday in March and the first Sunday in November.
Possible time zone change
The idea of a potential time zone change was floated in 2020, but nothing came of it. If it had been enacted, the standard time zone in the parts of Caudonia located within the United States would have been changed to UTC-5:30 and the daylight time zone would have been changed to UTC-4:30.
