I *thought* a day is defined as having 86,400 seconds (cf.
<http://www.bipm.org/en/si/si_brochure/chapter4/table6.html>).  If I am
mistaken in this view, please correct me -- I'll appreciate an
explanation or a link to one.

If you were referring to summer time issues, AFAIK this wouldn't be
relevant here, as the calculation is "internal", and the results
/should/ be faithfully presented in human readable form by calling
toLocalDateString().

One might argue, that it's even better to write it as

24 * 60 * 60 * 1000

what is not as efficient and short, but indicates the meaning even more
clearly.
