I can confirm this issue also for Natty 11.04 64bit but not with simple-scan but any PDF for instance produced by cairo, using "STRG-P" Print to file, like from Firefox, thunderbird and so on.
Going back to my old PDFs I saw this problem occurs for quite some time that all these PDFs have "Thu 01 Jan 1970 00:59:59 CET" as date of creation and last date of modification.
