timestamp

I'm using winscp3 release 3.7.4 build 271 with Foxit WAC server 2.0. When I do a put operation, either using windows interface or command line, files are stored on the server with a wrong timestamp ( a date near 20 february 1970) even if i configured the "preserve timestamp" option.

What is actual timestamp of file you are uploading? Can you try to play with option Misinterprets File Timestamps Prior to 1970 to see if it makes any difference?
