lrz in lrzsz-0.12.20(comms/lrzsz) sets invalid timestamp

When I send a file from Windows with Tera Term Pro and
	receive it by lrz on FreeBSD, the timestamp (modification
	time) of the received file is always set to 1991-Apr-20
	03:36:12 GMT (which may change according to compiler's
	optimization), neither the original file's timestamp nor
	the time that the file was transferred.
