I was with a group of Europeans last week and the issue of time zones came up. The US and Canada moved to an earlier application starting this year - second Sunday in March, instead of first in April. It will also revert later - first Sunday in November, instead of last in October. The first 3 weeks caused plenty of chaos to many IT departments, and I suspect this coming week will cause some more.
Of course, a heated debate ensued around my comment that any
given calendar date exists at some point on the globe for 50 hours. Discussing the vagaries of time zones with a jet lagged group whose first language is not English makes for some fine dinner conversation -)
