Title: server: Fix the signedness of the sent timestamp.

Re-reading RFC 868 reveals that the type of the timestamp is uint32,
not int32. int32 would not give us a range until 2036. So it has to be
unit32, whose maximum gives the correct number of seconds between 1900
and 2036.

Testing with rdate(1) confirms that all continues to work as expected.
