Parses the supplied datestamp parameter.  This parameter typically would
have been pulled from a longer FTP listing via the regular expression
mechanism
Params:
timestampStr – - the timestamp portion of the FTP directory listing
to be parsed
Throws:
ParseException – if none of the parser mechanisms belonging to
the implementor can parse the input.
Returns:
