Subject: bug#52525: wanted to add option to date command to handle pure numeric input in varying ways and output for invalid dates 
Date: Wed, 15 Dec 2021 20:39:04 +0000

I'm trying to implement the options shown below. I downloaded the coreutils source
for my distro and don't expect a problem compling and implementing it.
However, is there any interest in adding similar functions to the main code?

I would imagine something like,

date  --option=four-digits-are-YYYY,invalid-output-blank-line 

My immediate concern is getting this to take the input as a year rather than HHMM and
it would be easier to make date more versatile than put logic around it,

$echo 2000 | date +%Y -f-
2021

not sure if anyone else would want that.

Thanks.

Subject: the ubuntu "date" command info pointed me to you, question on modification

I wanted to add an option to the linux date command to
deal with pure number date stings - allowing for a 4 digit number
to be a year instead of HHMM - which should be easy
for me to do but I wanted to see how it integrates.
Also, I wanted an output option, that I could write, to
send an invalid message to stdout instead of stderr.

How should I proceed?

Thanks.
