海外向けのFlashベースのサイトの設計を進めているのだが、内部ではGMTもしくはUTCで時刻を管理しなければならない。今まで、TimeZoneに関して無頓着だったが、これは考えないといけない。

Flash remoting for PHP: A responsive Client-Server Architecture for the Web

Note that the returned dates from getClientDate and getServerDate should only be used with gmdate, as they are formatted according to Greenwich time. The timezone that is used is a global variable that is created before hand during unserialization; it is always the timezone in the last date encountered during unserialization. Therefore please be aware that the class may not work properly if you send several dates with different timezones during the same method call (why you would want to do that is beyond us).

その他、UTF-8と多言語表示に関して調査中。
