Strange issue with media.xml

pepak · 09-08-2008, 10:02 AM

I am writing myself an application for creating collections, and I have enountered a strange problem:

I need to fill in the 'date' attribute of <xs1:text> tag:

Code:

<xs1:text ... date="Wed, 03 Sep 2008 16:57:34 GMT" />

The date used is, curiously enough, file creation date rather than file modification date, but I can deal with that. The strange thing is that as far as file management utilities and Windows API in general, the file for the above example has a creation date of "03 Sep 2008 17:57:34" - which would be more or less correct since I am in a GMT+1 timezone. But: How does the Reader know that my timezone is +1? It can't be getting that information from its filesystem since it uses FAT and FAT does not store timezone.

I need to know because if I keep the date at the value I read from the filesystem, the Reader will think the file got changed and will rebuild the cache for it. I need it to accept the modifications I did to media.xml, and that means I need to set the correct date - which is different than the date in filesystem.

Any ideas?

There is a packet eBook Library sends to the Reader when it connects. It contains the PC's current time and timezone. Reader stores it in a local file.

Ah. That would explain how the reader knew about the timezone - I did run the Library once.

OK, I can handle that.
