FileTime \ModifyTime not updated

duesentrieb66 Ontario

I try to compare 2 files over their modify time. Unfortunately rapid is not updating the files until I restart the FTP server.

file1:=FileTime("ftpserver:/file1.csv" \ModifyTime);
file2:=FileTime("ftpserver:/file2.csv" \ModifyTime);

I set "trusted" to yes and no - makes no difference.
On any ftp client I can see the new date after a reload at the client - so it is not my ftp server (vsFTP on linux).

Any idea how to fix that?
