Time Zone problems with HTC wildfire S

[delano87]

Hey i have a problem.. I live in Guyana South America. when ever i text my frenz, when they reply the msg time will always say 3 hours later than the time i actually recieved it. even if i receive an immediate response. I've tried to change the time zones etc but the msg received time is always off. On my other friends phones, their time zoones would say GUyana Time but my time zone only says ATlanic and Bizillia etc, nothing close to Guyana time. Even if i change the time zone to the network settings the same still happens. How can i fix that or how can i get the correct time zone? is there a way i can download it or something??? Plz halp thanx..
