Thanks!

I wrote an if statement adding or subtracting an hour when I encounter this, so the problem is solved for me. But it's less than ideal that I have to write additional code to work around an important and widely used script function.

You have yet to demonstrate that there is actually a shortcoming anywhere outside of your own understanding. That is not intended as an insult; it's just an objective analysis of your postings in this thread so far. Consider that the only date example you've posted to demonstrate the "bug" actually returns the correct result.

If you believe that other invocations are returning an erroneous result, then post them. Also, it can't hurt if you list the exact date implementation and version used, and some information about your operating system platform.

And if this is part of a larger script, and if that script in anyway handles the date result before it's displayed, then post that code as well.

Regards,
Alister

NAME

       sulog - su command log file

SYNOPSIS

       /var/adm/sulog

DESCRIPTION

       The  sulog file is a record of all attempts by users on the system  to execute the su(1M) command.  Each time  su(1M) is executed, an entry
       is added to the sulog file.

       Each entry in the sulog file is a single line of the form:

	      SU date time
	      result port user-newuser

       where

       date	       The month and date su(1M) was executed.	date is displayed in the form  mm/dd where  mm is the month number and dd  is  the
		       day number in the month.

       time	       The  time   su(1M) was executed. time is displayed in the form  HH/MM where  HH is the hour number (24 hour system) and	MM
		       is the minute number.

       result	       The result of the  su(1M) command.  A ` + ' sign is displayed in this field if the su attempt was successful; otherwise	 a
		       ` - ' sign is displayed.

       port	       The name of the terminal device from which  su(1M) was executed.

       user	       The user id of the user executing the  su(1M) command.

       newuser	       The user id being switched to with  su(1M).

       SU 02/25 09:32 + pts/3 user1-root
       SU 03/02 08:03 + pts/5 user1-root
       SU 03/03 08:19 + pts/5 user1-root
