I noticed the time stamps used by the Google App Engine to show the application logs were all in the Pacific Standard time Timezone. That’s just not useful for everyone not living in the pacific coast.
So I wrote an user script you can use to show the time stamps in your browser’s timezone.
I tested my script on Firefox with greasemonkey and google chrome and it seems to work.
You can get it here: http://github.com/simao/mycode/raw/master/UserScripts/appenginelogtz.user.js
You can also fork this script at github and change it. If you do, please push your changes back to the repository. :)
