True.  But there's a workaround in this case:

$ /usr/bin/uname -sr
Darwin 10.8.0
$ /bin/date
Wed 25 Jan 2012 14:38:44 GMT
$ /bin/date -v -1d +'%F'
2012-01-24

The -v option to date(1) in FreeBSD and Mac OS X takes an "adjustment"
to apply to the date before printing it; in this case, we adjust by
subtracting one day ("-1d").  Then the %F date format shows just the
date, as desired.

Yes, often.
