new message if php timezones-library is not installed

[neoxx]

a minor thing: we're not lame anymore ;) ... - i suggest to change the message if the daylightsaving cannot be automatically set to enforce the users to get in contact with their web hosts rather than blame wordpress.

(In [13990]) We're not lame if they don't have the PHP 5 DateTime library. Change the message when there is no timezone support. props neoxx, fixes #12580.

Some guidance on what is meant by "The PHP Date/Time library" would be more useful - a Google Search for that returns this page, and references to a bunch of work arounds.

What exactly is WordPress checking for? Hosts are going to be a lot more helpful when asked to install something specific, rather than something a bit vague.

Just to update - I installed the pecl extension timezonedb - that doesn't fix it. There is no mention of any such "requirement" or suggestion in the documentation as I can find it, so please specify what is meant by php timezones-library or php date/time library, or at least use the official name of whatever it is, so that a Google search is likely to return the correct fix. Thanks.

Take a look at ​wp_timezone_supported().

Updating to PHP 5.2 should handle this. AFAIK the functions we need are all core functions, not in an extension (though of course any function can be disabled). the PECL library allows you to update your timezone list but it is not the library.
