invalid date from date -d 1969-12-31

[Stan Heckman <stan@stanheckman.com>]

On my system, date -d returns "invalid date" for dates before 1970. It
is possible that this began when I upgraded libc6. Any suggestions?

$ date -d 1969-12-31
date: invalid date `1969-12-31'
$ date -d 1970-01-01
Thu Jan  1 00:00:00 EST 1970
$ uname -srpmvi

$ dpkg -p coreutils | grep Version

$ dpkg -p libc6 | grep Version
