The parser for "set timestamp" was upgraded on 2005-07-27 from
the old version 3.7 fixed-order option syntax to the newer
options-in-any-order syntax of version 4.  As with all(?) other set
commands, the "offset" keyword is now parsed by the shared routine
get_position_default().

But the documentation was not updated to match.
=46ixed in CVS for 4.2.1 and 4.3
