In PageDateTag.java, the DEFAULT_FORMAT needs to include the milliseconds like this:

public static final String DEFAULT_FORMAT = "dd-MMM-yyyy HH:mm:ss:SSS zzz";

Without those milliseconds, we cannot programmatically edit a wiki page because the page modified dates do not match.

Not a bug. You need to do a GET of the Edit.jsp page first to receive the page modification date in the "edittime" parameter. If you want to do a GET to a Wiki.jsp page, and assume some specifics about its layout, then you should make your own template.
