It can easily be done without Python. I just happen to prefer Python and wrote Alfred-Workflow in it. If you want to use another language, you'll either want to find a similar library that can do the XML generation and searching/filtering for you (good luck with the latter), or you'll have to write a lot more code yourself.
 
In any case, I wrote a simple version for you. Download the workflow from the releases page.

UPDATED to v1.5
 
Hey guys, fairly significant update here - the workflow now uses Google Maps APIs to get the timezone data, which you should find substantially more reliable than Wolfram Alpha.
 
Also, FLAGS! 
     
See the first post for detailed changelist and download link.
 
PLEASE NOTE: Because this version stores its data substantially differently to previous versions, it will create a new timezones.txt file with default cities. However, it will attempt to save your old timezones.txt file to your Desktop, so you should be able to rebuild your previous list without too much hassle. Sorry for any inconvenience.

Hi,
 
Can I put a line break in so that the log entry has a title and then body text?
Thanks
