Files with negative timestamps appear as 0 byte broken aliases

Files on a remote system which have a negative timestamp are broken when mounted with ExpanDrive. Under Finder, they show as Zero KB Alias files which you cannot Get Info on or perform operations with. Any attempted operations with the file over ExpanDrive from the shell result in "Invalid argument".

Example output of `find . -printf "%p: %T@\n"` (outputs modification time as seconds since epoch) when logged in to remote (Linux) system via SSH:
./filename: -1

Same file in Finder over ExpanDrive mount in attached screenshot.
