in the PHP core. This is the new implementation of PHP's datetime support.
Although it will attempt to guess your system's timezone setting, you
should set the timezone manually. You can do this in any of three ways:
</P

></P
><UL
><LI
><P
> in your <TT
CLASS="filename"
>php.ini</TT
> using the
<A
HREF="missing-stuff.html#ini.date.timezone"
>date.timezone</A
> INI directive
</P
></LI
><LI
><P
> on your system using the <TT
CLASS="constant"
><B
>TZ</B
></TT
> environmental variable
</P
></LI
><LI
><P
> from your script using the convenience function
<A
HREF="function.date-default-timezone-get.html"

> All supported <A

in the PHP Manual.
</P

> With the advent of PHP 5.2.x, there are <A
HREF="language.types.object.html"
><B
CLASS="type"
>object</B
></A
> representations of the
date and timezone, named DateTime and DateTimeZone respectively.
The methods map to existing procedural date functions.
