What are the implications (problems) of these differences in time to a manager in London, Ontario who might need to coordinate a conference call among the following three locations: London (Canada), London (England), and Sydney (Australia)?

Answer 1

When it's 9 a.m. in Ontario, it's 2 p.m. in England. So far so good -- but it's 1 a.m. in Sydney, Australia.
