I've been unable to download the full mail archive to search it for things 
like this.  However, I just now found gmane.org so I'm now able to search 
the archive.  I see that there has been a lot of talk about the labels, 
but I think my question is different, as I'm not asking if it should be 
changed.  I accept EST, and that's that.  I mean...isn't this set by the 
laws of the area in question?  Nothing we can do about that...right?

I was wondering more about the usage of the string EDT by the websites, 
which, to me at least, appears wrong.  It made me wonder how 
dateandtime.com and worldtimeserver.com are arriving at this label...if, 
in addition to the tz database, they're maybe including cultural usage 
considerations into the results.  I'm hoping that Steffen Thorsen may 
respond and explain the result.

The EDT usage piqued my interest because of a similar situation in the US 
with postal addressing.  There are cities who are referenced by a common 
name instead of their official name...and the better commercial ZIP code 
databases will include a list of alternate names for cities.  So I was 
wondering if this was a similar situation of there being an alternate 
common usage, and possibly a list of common labels alternates somewhere.
