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

|
</para>

<para>
|
|
Instead of using this function to set the default timezone in your script,
|
|
you can also use the INI setting <link
|
|
linkend="ini.date.timezone">date.timezone</link> to set the default
|
|
timezone.
