Thank you for the bug report. However I am unable to reproduce it.
Therefore I conclude that the problem must be related to your
timezone. Because you are taking dates a midnight I am guessing that
there is very likely a daylight savings time issue there. (Was
Daylight Savings Time active then?) Instead, try looking at dates at
noon.
date -d '1991-04-14 12:00 +1 day'

I am sorry that I am not familiar with those timezones. What is the
time there that would allow me to recreated it on my system? Either
for a TZ variable setting or a setting for /etc/localtime? For
example either TZ=Americas/Denver or TZ=US/Mountain would configure my
personal timezone.
