cflib icalUS seems only taking care of the US daytime savings, is there a global thing i can change so it reflects all countries timezoine or atleast make the time GMT enabled so it always displays in GMT instead of every country timezone, but if timezone can be done, it will be much better

Yer not giving much context to this, but if "always displays in GMT" works, then... set your server TZ to be UTC. And date/times that the CFML server creates use the server TZ.
