As an obsolescent calling convention, if this function is called with
6 or more arguments, the first 6 arguments are SECOND, MINUTE, HOUR,
-DAY, MONTH, and YEAR, and specify the components of a decoded time,
-where DST assumed to be -1 and FORM is omitted. If there are more
-than 6 arguments the *last* argument is used as ZONE and any other
-extra arguments are ignored, so that (apply #\\='encode-time
-(decode-time ...)) works. In this obsolescent convention, DST and
-ZONE default to -1 and nil respectively.

Years before 1970 are not guaranteed to work. On some systems,
year values as low as 1901 do work.
