三藩市應為 Pacific Time zone, 不是 Eastern Time Zone, 雖然數字計算是正確.

I don't know where you in the website you got such piece of information, but New York is EST, San Francisco is PST.

To 005, where in wikipedia said San Francisco is EST?

http://en.wikipedia.org/wiki/San_Francisco

At the bottom of the box on far right, it says PACIFIC STANDARD TIME, or PACIFIC DAYLIGHT TIME during Daylight Saving period.

正確是: 2:30 am
