bug#35289: date+%-Y -d "- N years" errors when N > 111

[O. Emmerson]

I have been using 'date +%-Y -d "- 2010 years" in a script for years but
today after using the script after upgrading to Ubuntu 19.04 it has failed.

After some experimentation it succeeds with upto 111 years but fails
from 112 onwards.

Error given is:

'date: invalid date '- 112 years'.


DistroRelease: Ubuntu 19.04
Package: coreutils 8.30-1ubuntu1

I have already reported the bug in Ubuntu
(https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/1824688) but
they have advised me to report it here.

Regards
