[TxMt] Blogging Bundle & WordPress Time Stamps

[Mark N. Boszko]

Has anyone else gotten this effect?

I post to my blog with the TextMate blogging bundle (thanks, Brad!),  
and if I go to re-edit a post, the timestamp changes. As far as I can  
tell, that's related to me getting back a timestamp in the TextMate  
document that says something like:

Date: 2008-01-19 16:32:44 -0500

...which is roughly 9:30pm EST, according to my blog. If I re-publish  
that post from TextMate with that datestamp in there, it suddenly then  
becomes:

Date: 2008-01-19 11:32:44 -0500

...which shows up as roughtly 4:30pm. If I edit a post multiple times,  
it keeps subtracting 5 hours, to the point that I can even end up at  
the point of it having been posted the previous day.

Do I have something set up wrong here, or is there a workaround?

Thanks for any help!

Cheers,
MB
