Extra space in openssl CLI output for notAfter/enddate

[nikolaiderzhak]

I am getting extra space in enddate output of this command:

$ export IP=google.com;  nc -z -w 3 $IP 443 && (echo | openssl s_client -connect $IP:443 2>/dev/null | openssl x509 -noout -enddate)
Connection to google.com port 443 [tcp/https] succeeded!
notAfter=Apr  4 09:40:00 2018 GMT

Note two spaces between Apr and 4 in notAfter= line.

That is the case for both versions I have on laptop and on linux server:

$ openssl version
LibreSSL 2.2.7
$ openssl version
OpenSSL 1.0.1f 6 Jan 2014

OpenSSL has the same issue: openssl/openssl#5107

This question was answered in openssl/openssl#5107 . Can you close this issue ?

This is pretty much how dates work on Unix and C - the day is formatted as two digits with leading padding, hence a single digit day will be formatted as ' 4'. This is the same date(1) and ctime(3):

$ date -r 1516500000 
Sun Jan 21 13:00:00 AEDT 2018
$ date -r 1515000000 
Thu Jan  4 04:20:00 AEDT 2018

(Or date -d @1515000000 on a Linux system).

Is there a reason why you consider this to be a problem?

We using enddate string to confirm SSL certificate is taking care of and visually strings with one and two spaces looks the same while we get them different in process. Thank you for explanations !
