The tz database is a public-domain database of time zones for locations around the world. Each location is identified by continent or ocean, and then by the name of the largest city in the region. For example, “America/New_York” represents the US eastern time zone. The string “America/New_York” is the tz name for the region. Each tz name represents the local time for that locale. See Understand time zone names for a list of tz values you can use in Genesys Cloud.
