问题
I can't seem to find a way to get Pear's Date class (or PHP's date function) to return AEST as the timezone abbreviation for the timezone Australia/Melbourne. It always returns EST. I tried all the ways of printing out the timezone available in Date::format, format2, format3. Anyone know how to fix this? I'm running PHP 5.1.6, Pear Date 1.5.0a1, and the latest PECL timezonedb.

Have you checked what it says in the time zone database for Australia/Melbourne? It is probably based on the Olson database, and when I last looked (2009a edition), it was still saying EST is the abbreviation for Australia/Melbourne. So, unless you have fixed the time zone database to say AEST, it is likely to continue to say EST. This has been debated on the TZ mailing list a few times; there isn't a settled answer, so the abbreviation remains unchanged.
