I ran the raw directory list through my list parser and the date/time is properly extracted and set correctly for downloads.
I'm really not sure where 1980 would be coming from or why the date/time would be wrong.
What is the last version/build of FlashFXP that worked correctly for you?
You can check our FlashFXP archive for previous builds for testing
