 A contributor to the Maxima project bumped into this while trying
 Maxima + ABCL 1.4.0.

 CL-USER(2): (ENCODE-UNIVERSAL-TIME 48 1 15 15 8 1995 -13)

 CL-USER(5): (ENCODE-UNIVERSAL-TIME 48 1 15 15 8 1995 'foo)
 3017516508

 Not too surprising, I think -- a glance at
 ./src/org/armedbear/lisp/time.lisp shows that the TIME-ZONE argument
 doesn't take part in the calculations.

 TIME-ZONE does come into play in pre-r14840  versions of time.lisp and the
 results are consistent with other CL implementations, at least for the
 examples exercised by the Maxima test suite (date parsing).
