But surely you have read ECMA 263 3 & 5, and ISO/IEC 16262, from one end
to the other ?

Multi-argument setters are included in
<URL:http://www.merlyn.demon.co.uk/js-dobj2.htm>, probably correctly.

For any methods and arguments given in ECMA 3, which was finished by
late 1999 and presumably available in draft to browser-writers before
them, one should expect implementation in all reputable "full" browsers
in all vaguely current versions.

I've frequently used (and probably posted here??) setFullYear with YMD
and setHours with hms - and never noticed any problem; and I've never
AFAIR seen any problem reported.

However, Firefox 2.0.0.3-16 treated D < 1 as D = 1 in Date.UTC(Y,M,D)
(Firefox 3 is OK) and in retrospect it would have been well to test the
set routines above (and set[UTC]Date) with D = 0.
