Re: Date formats in XML for Excel Spreadsheet download?

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Vicki - I might be able to help if I have a little more detail.

Are you talking about the 2003 Spreadsheet XML format for Excel?

Are you using CGIDEV2 or some similar tool to write the XML?

Or are you doing something different? Like does Excel read the XML directly?

Anyhow, Excel stores dates and times as numbers, known as serial 
numbers, the dates are the number of days after (or since?) Jan 1, 1900 
(or 1904, if you set it up that way).

Hope I'm anywhere on the same planet as you are!! Glad to help if I can. 
I've been doing a lot work with Excel lately, so may actually know 
something.
