Understand time zone names

AI-generated summary

Genesys Cloud enables users to specify time zones in Outbound campaign contact lists using custom time zone names configured for callable time entries within contactable time sets. Time zones are designated using Tz database notation (IANA Time Zone Database), a public-domain naming convention that identifies locations by continent or ocean followed by the largest city in the region, such as America/New_York, Europe/Paris, or America/Indiana/Indianapolis. Each Tz name represents the local time for a specific locale, with regions separated based on local clock consistency since 1970. Users should note that the AutomaticTimezone-Phone column in the contact list editor may display notation different from exported Microsoft Excel files—for example, displaying Etc/GMT+6 instead of UTC-06:00—though both notations represent the same time zone offset. As of November 1, 2026, British Columbia (UTC-7) and Alberta (UTC-6) will transition to Permanent Daylight Saving Time. Genesys Cloud supports an extensive list of time zone names for use when agents schedule callbacks or administrators populate zone columns in contact lists. The supported time zones encompass regions across Africa, the Americas, Antarctica, Asia, the Atlantic, Australia, Europe, the Indian Ocean, and the Pacific, with specific designations for standard and daylight saving time variations. Additionally, Genesys Cloud recognizes generic Etc/GMT time zone formats with UTC offset pairs, including Etc/GMT+4 (UTC-04:00), Etc/GMT+6 (UTC-06:00), Etc/GMT+8 (UTC-08:00), Etc/GMT+11 (UTC-11:00), Etc/GMT-12 (UTC+12:00), Etc/GMT-9 (UTC+09:00), and Etc/GMT-10 (UTC+10:00). Many time zones are marked with asterisks to indicate support on Microsoft Edge. This comprehensive time zone coverage enables proper scheduling and contact management across global operations.

Coming November 1, 2026: British Columbia, Alberta, Manitoba, and the Northwest Territories adopted permanent Daylight Saving Time. This change means that the time in these regions will no longer fall back in November.

For more information, see What time zone should I select for Canadian provinces that adopted permanent Daylight Saving Time on November 1, 2026?

You can specify time zone names in an Outbound campaign contact list using custom time zone names you previously configured for callable time entries of contactable time sets in Genesys Cloud.

You can specify the time zones in callable times entries along with custom names. Time zones are in Tz database notation, a public-domain set of zone names for locations around the world. This uniform naming convention is also called tzdata, zoneinfo database, or IANA Time Zone Database.

The process identifies each location by continent or ocean and then by the largest city in the region. For example:

America/New_York
Europe/Paris
America/Indiana/Indianapolis

The world separates into regions where local clocks have not changed since 1970. Each Tz name represents the local time for a locale.

Note: In some cases, the AutomaticTimezone-Phone column in the contact list editor displays a notation that is different from the notation you see when you export the contact list and view it in Microsoft Excel. For example, you may see UTC-06:00 in the exported list, but the contact list editor displays Etc/GMT+6. In both cases, the time zone is six hours behind Coordinated Universal Time. This applies for the following pairs of time zones.

Etc/GMT+4 – UTC-04:00
Etc/GMT+6 – UTC-06:00
Etc/GMT+8 – UTC-08:00
Etc/GMT+11 – UTC-11:00
Etc/GMT-12 – UTC+12:00
Etc/GMT-9 – UTC+09:00
Etc/GMT-10 – UTC+10:00
