Yes. In my case, I need to get TZ offset as of Jan 1, 1970. And sometime we pass a minus number to getOffset(), like -3600000. I'm not sure Alaska timezone will be GMT-10 in 1970. Thanks for your information. I will search more to find the result. Thank you very much. -- Best Regards, TANG Jiyu Blog: http://jiyu.wordpress.com.cn/ ezkeypad: http://ezkeypad.tool100.com/ -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
