date: illegal option -- j (Mac OS X 10.4.11) #497

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: DATE(1) BSD General Commands Manual DATE(1)

NAME date -- display or set date and time

SYNOPSIS date [-nu] [-r seconds] [+format] date [-u] mmddhhmm[[cc]yy]

DESCRIPTION date displays the current date and time when invoked without arguments. Providing arguments will format the date and time in a user-defined way or set the date. Only the superuser may set the date.

 The options are as follows:

 -n      The utility timed(8) is used to synchronize the clocks on groups
         of machines.  By default, if timed is running, date will set the
         time on all of the machines in the local group.  The -n option
         stops date from setting the time for other than the current
         machine.

 -r      Print out the date and time that is seconds from the Epoch.

 -u      Display or set the date in UTC (universal) time.
 An operand with a leading plus (``+'') sign signals a user-defined format
 string which specifies the format in which to display the date and time.
 The format string may contain any of the conversion specifications
 described in the strftime(3) manual page, as well as any arbitrary text.
 A <newline> character is always output after the characters specified by
 the format string.  The format string for the default display is:

       ``%a %b %e %H:%M:%S %Z %Y''.

 If an operand does not have a leading plus sign, it is interpreted as a
 value for setting the system's notion of the current date and time.  The
 canonical representation for setting the date and time is:

       cc      The first two digits of the year (the century).
       yy      The second two digits of the year.  If ``yy'' is specified,
               but ``cc'' is not, a value for ``yy'' between 69 and 99
               results in a ``cc'' value of 19.  Otherwise, a ``cc'' value
               of 20 is used.
       mm      The month of the year, from 1 to 12.
       dd      The day of the month, from 1 to 31.
       hh      The hour of the day, from 0 to 23.
       mm      The minute of the hour, from 0 to 59.
       ss      The second of the minute, from 0 to 61.

 Everything but the minutes is optional.

 Time changes for Daylight Saving and Standard time and leap seconds and
 years are handled automatically.

ENVIRONMENT VARIABLES The following environment variables affect the execution of date :

 TZ  The timezone to use when displaying dates.  See environ(7) for more
     information.

FILES /var/log/wtmp A record of date resets and time changes. /var/log/messages A record of the user setting the time.

EXAMPLES The command:

       date "+DATE: %m/%d/%y%nTIME: %H:%M:%S"

 will display:

       DATE: 11/21/87
       TIME: 13:36:16

 The command:

       date 061316271985

 sets the date to ``June 13, 1985, 4:27 PM''.

 The command:

       date 1432

 sets the time to 2:32 PM, without modifying the date.

DIAGNOSTICS The following exit values are returned: 0 The date was written successfully (either locally or globally) DIAGNOSTICS The following exit values are returned: 0 The date was written successfully (either locally or globally)

0 An error occurred.

 Occasionally, when timed(8) synchronizes the time on many hosts, the set-
 ting of a new time value may require more than a few seconds.  On these
 occasions, date prints: `Network time being set'.  The message
 `Communication error with timed' occurs when the communication between
 date and timed fails.

LEGACY SYNOPSIS date [-nu] [-r seconds] [+format]

      [[[[[cc]yy]mm]dd]hh]mm[.ss]

LEGACY DIAGNOSTICS When invoked in legacy mode the following exit values are returned: 0 The date was written successfully 1 Unable to set the date 2 Able to set the local date, but unable to set it globally

STANDARDS The date utility supports the Version 3 of the Single UNIX Specification (SUSv3''). It is also expected to be compatible with IEEE Std 1003.2 (POSIX.2'').

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 date command on MAC OS 10.4.11 doesn't support what we need and without any way I can test I'm reluctant to try and use an alternative command.

I use this awk program to mess with date ranges in my certificate script rather than trying to get date to work nicely everywhere. It works for Gregorian calendar dates from year one up on any awk derived from the '88 nawk version (basically all of them).

This gives "TODAY" $ jdayjdat $(date '+%d %m %Y') This gives "end date" $ jdayjdat $(openssl x509 -noout -enddate -in cert.pem | sed 's/^[^=]*=//' | awk '{print $2,$1,$4;}')

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.
