"2nd March 2012; 3pm to 6pm" - so that's 8am to 11am tomorrow, here in the UK and 3am to 6am if you're on the East Coast of the USA. I can see some North Americans getting up early tomorrow!
Close, but Shanghai is GMT +8, Eastern Canada/America is GMT-5. 15:00 there will be 02:00 here.
And, converting other numbers $4200 AUS = $4463 CDN!
