I have noticed that %-N when used with the data command no longer
appears to always remove leading zeros, instead it appears to be
removing trailing zeros? Obviously, removing trailing zeroes will
changes it value.
From the date manual '(hyphen) do not pad the field'
As an example of this...
for i in {1..100}; do date +'%-N'; sleep 0.01; done
...can return the following values.
