Hi @etanol85 It's a benign error as that piece of code just checks whether the certificate needs renewing, when it fails the code just renews the certificate. I've spent some time researching this and the |

Thank you timkimber and rdebath! I just tried rdebath jdayjdat awk script, but it seems not to display the date correctly. When I ran jdayjdat $(date ’+%d %m %Y’) it prints 2459026 and today it is 26-06-2020, date gives: Fri Jun 26 09:02:29 CEST 2020 Am I missing something? |

Hi @etanol85 I found out recently that github actions support MacOS so I'll write a test for this scenario and post an update. |
When running getssl mydomain.com under MAC OS 10.4.11
I see the folowing error:
usage: date [-nu] [-r seconds] [+format]
date [[[[[cc]yy]mm]dd]hh]mm[.ss]
The script seems to continue despite this error but I don’t know if it works correctly.
man date gives:
