InitializeDateTimeFormat only determines which date time components will be shown how in formatted strings. The actual conversion from a date (a number of milliseconds from January 1, 1970, midnight UTC) to corresponding year/month/day/hour/minute/second values is done by the ToLocalTime abstract operation, which is specified to take the time zone into consideration. The FormatDateTime abstract operation combines the output of the two to produce a final formatted string.

> Looking at the steps involved, you haven't taken account of the time zone offset when you pass step 28, so you can't omit setting the hour internal property, even if you're not going to display the hour field in the resulting format. That is, "2012-08-15T22:00:00Z" wants to display as "August 16, 2012" with a time zone of "Asia/Tokyo". Or did I miss something?
