Daylight savings time has started in the USA (↑) today.
In Europe it will begin in two weeks, and it will end in Australia in three weeks.
Especially if you are in Europe you could easily miss online events in the USA during the next two weeks.
Be aware of those time changes when planning or attending online events.
Here is why.
For example, when it is 1pm in New York it is usually 6pm in London. Between March 14 and March 27, 2010, however, it will be 5pm in London, only 4 hours later.
Then on
March 28 daylight savings time will rule on both continents and time difference will be the usual 5 hours till the clocks will be reset in fall of 2010, again.
Life could be easier if daylight savings time were changed on the same weekends all over the world, but that's not the case.
To make things worse, Hawaii (and many other regions in the world) don't observe daylight savings time at all. On top of that Australia and New Zealand are on the southern hemisphere. While we start daylight savings time in the North, Australia will end it on April 4, 2010.
Tip: TimeAndDate.com (↑) offers detailed information and tools. Like a timezone converter, etc., …
Personally I am adding timezone information to event details. Don't leave room for assumptions. Don't assume your readers are educated about timezones, it's your job to communicate in a way they understand easily.
Here is an example for unambiguous event information.
Webinar starts on Friday, March 12, 2010 at 3:30 p.m. EST (UTC-05) as in New York, USA
or
Teleclass starts on Wednesday, March 17, 2010 at 3:30 p.m. EDT (UTC-04) as in New York, USA.
Note: EST is Eastern Standard Time and EDT is Eastern Daylight Savings Time.

P.S.: Especially US marketers seem to be unaware of — or lazy about — timezone issues that go beyond Eastern versus Pacific time. Check out my previous post on this subject:
