想問下EST同PST時區同香港時間的轉化問題?

愚問: 想問下EST同PST時區同香港時間的轉化問題?
我reg左d online seminar 話
January 8, 2010
11:30AM EST
8:30AM PST

想問下香港時間實際邊一日幾多點?
一月EST 同PST 係咪有分冬令時間?

thanks in advance.

I could be completely off but I believe HK is 16 hours ahead of Los Angeles, which is under the Pacific Time Zone.  

So if your seminar begins at 830am PST, then it is actually 1230AM in HK, January 9th.

所謂的冬令時間，其實即係唔行夏令，用返本身個時區
所以 PST 即係慢香港 16hr, EST 慢 13hr

thank you for both advices.
very useful!
