Description:
------------
There is currently no information about the supported timezones from the datetime section of the manual. Also from the timezone listing there is no link to the pecl::timezonedb package. So users might be misled to believe they need to upgrade PHP to update their timezones.

The following patches are untested and probably need some tweaking from a phpdoc/docbook expert. 

Reproduce code:
---------------
add link to supported timezones to date_default_timezone_get()
