I started using ScribeFire to write my blog posts a long time ago. I actually started using the add-on when it was called Performancing. It is pretty handy and allows me to compose at my leisure and to not worry about a browser crashing. Saving my work as I go is nice and easy as well.
A recent version of the add-on has introduced some strange side-effects. Before the new version my posts would be accepted by my site without a problem, and would show up with the appropriate time stamp.
Now when I post, the new posts are showing up with a timestamp 7 hours later than what I expected. My Drupal install has a setting to indicate what timezone I want my site to operate in, and right now it is set to GMT -7.
Perhaps the problem is in Drupal and maybe it is in ScribeFire. When I have time I will install WireShark and examine what is actually posted to Drupal.
