here is a time zone list, classified by increasing offset from Coordinated Universal Time (UTC). The countries and regions observing a respective time zone are listed in the corresponding paragraph.
Regions marked with an asterisk (* in the northern hemisphere, ** in the southern hemisphere) are those that observe daylight saving time: 1 h in summer. In this case, the time zone shown is the one the region is in when it does not apply daylight saving time.
The expressions used to define certain time zones ("Central European Standard Time", for example) are not official and are most often translations of traditional English expressions. More detailed information, especially for states spanning multiple zones, can be found in the "Time Zones" section of the country articles.
