# date_default_timezone_set

## Descrizione

bool date_default_timezone_set ( string timezone_identifier )

date_default_timezone_set() sets the default timezone used by all date/time functions.

> Nota: Since PHP 5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a `E_NOTICE` if the timezone isn't valid, and/or a `E_STRICT` message if using the system settings or the TZ environment variable.

## Elenco dei parametri

timezone_identifier

  The timezone identifier, like UTC or Europe/Lisbon. The list of valid identifiers is available in the Appendice H.

## Valori restituiti

This function always returns `TRUE` (even if the timezone_identifier isn't valid).
