What scenery files are changed by FS Real Time?

Hi,I've been having some problems with FS Real Time (1.89) and would like to uninstall it but one thing struck my mind...since I chose the option "Check for DST changes in S. Hemisphere" in FS Real Time if I understood it correctly some of the scenery files in FSX were changed due to this.Does someone know what files are affected by chosing that option so I can hopefully replace them with the original ones or is this maybe done by the uninstallation program for FS Real Time? Also maybe worth mentioning is the addons I'm using...ASA, GEX, REX, FS Genesis Mesh, Ultimate Terrain USA and Europe.Thanks in advance!
