%-N is intended to be used after a decimal point, so removing trailing zeros 
does not change its value in its intended use.

Using...

date (GNU coreutils) 8.32

uname -a

Linux server 4.19.114-1-MANJARO #1 SMP Thu Apr 2 17:04:36 UTC 2020 
x86_64 GNU/Linux



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.
