[COGITO PATCH] value too great for base (error token is "-0800")

Hello!

The current cogito has problems with timezones that are too far from the
Greenwich meridian :-)

Bash interprets numbers beginning with 0 as octals.  Therefore, we need
to strip leading zeroes or zeroes following "-".  But if we get too
zealous and strip all digits, we'll need to restore one 0.  I tried to
write for sed portably, so I avoided some optimizations, such as
s/^-\?$/0/
