A DateTimeZone object provides access to three different types of timezone rules: UTC offset (type 1), timezone abbreviation (type 2), and timezone identifiers as published in the IANA timezone database (type 3). The DateTimeZone object can be attached to DateTime and DateTimeImmutable objects to be able to render the timezone encapsulated by these objects in a local timezone. &reftitle.parameters; timezone One of the supported timezone names, an offset value (+0200), or a timezone abbreviation (BST). &reftitle.returnvalues; Returns DateTimeZone on success. &return.falseforfailure.style.procedural; &reftitle.errors; This method throws DateInvalidTimeZoneException if the timezone supplied is not recognised as a valid timezone.
