Bosnia and Herzegovina uses a single time zone, denoted as Central European Time (CET: UTC+01:00). It also observes summer time, shifting to Central European Summer Time (CEST: UTC+02:00).
The shift to Daylight Saving Time (DST) occurs on the date as specified for the European Summer Time since 1983, when the system was introduced in the former SFR Yugoslavia. [1]
The IANA time zone database contains one zone for Bosnia and Herzegovina in the file zone.tab, named Europe/Sarajevo. [2]
Central European Summer Time, sometimes referred to as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time, Egypt Standard Time and Kaliningrad Time in Russia.
Time in the Czech Republic is given by Central European Time and Central European Summer Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October.
