I'm testing my zone conversion process and I thought I could just check the conversion with the Internet. So I get local time for Sydney, Australia, and then check my result with internet searches by searching for "time in Sydney Australia." Bing returns Current time in Sydney, New South Wales, Australia It is currently 11:31:34 AM on 10/30/2011 (AUS Eastern Daylight Time) Google returns 11:31am Sunday (EST) - Time in Sydney NSW, Australia Time oriented sites... timeanddate.com returns Sunday, October 30, 2011 at 11:31:34 AM EDT worldtimeserver.com returns 11:31 AM Sunday, October 30, 2011 Eastern Daylight Time (EDT) +1100 UTC (I selected both of those because they're referenced in the australasia data.) The two websites returned "EDT", and Bing implies "EDT" with its "Eastern Daylight Time." I thought I had a bug, but review of the tz database clearly states otherwise...it's "EST". Google was the only one to get it right (according to the tz database, that is.) So I'm wondering if anyone knows if there is some unwritten accepted practice of referring to Australian daylight saving time as EDT in colloquial speech, even though that labeling doesn't actually exist. Any thoughts on the subject are appreciated.
