Synchronization Overwriting All Files

Hi, I am a new user and am having difficultly synching the files between the remote and my local drive. The ftp server is in GMT and I am in EST. I have enabled "Keep File Time" and created a rule that overwrites only destination files with an older date. The problem is all files are continuously replaced, because it seems that the "Keep File Time" is not working (the files are given a new date time (EST) as there are transfered).

What am I doing incorreclty?

Thanks for your help
