PHP 5.1.6 errors if EXPERIMENTAL_DATE_SUPPORT enabled

[vipsoft]

Installer:

• detect whether or not DateTime classes available; otherwise

  Fatal error: Class 'DateTimeZone' not found in /home/apang/work/piwik/dev/trunk/core/Date.php on line 207
  

• see  http://ca2.php.net/manual/en/datetime.installation.php re: building PHP with: CFLAGS=-DEXPERIMENTAL_DATE_SUPPORT=1

Note: I have some more testing to do and may expand on this ticket...

Hmm... the DateTime and DateTimeZone classes aren't in the 5.1.6 sources (but the timezone functions are). I'm guessing some distros either backported this feature or used a post-5.1.6 SVN shapshot.

Options:

• raise minimum php requirement to 5.2, or
• modify core/Date.php to not depend on DateTime & DateTimeZone

(In [2186]) fixes #1359 - use procedural interface instead of DateTime & DateTimeZone classes to support php 5.1.6 with experimental date support enabled
