We're posting a link to our seminar on our blog for March the 17 2PM EDT.

This link goes out internationally, so how do I show local time to people from other states and other countries?

You can see the full-size video here.

this is a very very useful post...especially when you are dealing with global viewers...

That sounds like a very useful resource.

I find myself questioning my computer settings and those of people who've sent me emails even from my own time zone, wondering when they were sent. I wonder if there's a way to tell when someone sent an email if settings aren't accurate, after the fact?

The email records when it arrived in your inbox. So there's no need to know the time zone of the sender, the time stamp on the email tells you when it arrived.

Even if you don't immediately download the emails to your email client (Outlook, Mozilla Thunderbird, etc.) the email server will still include the right timestamp.
