@artfuldodga, the next release will have custom time format support, so you can change it yourself...
I allready know about the shift when the contact uses emoticons, and I allready fixed that...
So I don't know what the problem is, could you make a screenshot? and are you using a custom skin?
@Mattike, as I said in the first post, the value is lost whenever you close/restart the script, and that I will fix that in the next release (90% chance it will be today). And so I did, I fixed that, and am working on more customization now....
The next release will be available before 19:00 UTC (in 7 hours and 30 minutes)
