How to Set Timezone in PHP? (Timezone List)

“Timezone” refers to a particular geographical region in which time is kept. Timezones are generally defined by their offset from UTC, or Coordinated Universal Time. In PHP, you can use the date_default_timezone_set() function to set the default timezone for your script.

UTC, or Coordinated Universal Time, is the primary time standard by which all other timezones are defined. It is sometimes also referred to as GMT or Greenwich Mean Time. UTC is a worldwide time standard that is based on an atomic clock.

//use timezone name with PHP date
date_default_timezone_set('America/Anchorage');
$datetime = new DateTime('2022-05-22T05:30:00', new DateTimeZone('America/Cordoba'))

The following is a list of timezones:
