I have an assignment in a Linux class I am taking. It has multiple scripts. Basicly when it runs it asks the user name and shows information about the user from the /etc/passwd and /etc/shadow files. The one I need help with is the one that reads the /etc/shadow file. I need to format the date into something that is readable and means something to everyone.For this assignment everything is to be done as an awk script.
here is the line from the script with the date that I need to format
the number that shows up for "$3" which is supposed to be the date is 14985
I need to format that date into something like May 5, 2011 but as the date it actually stands for.
I have a comma delimited log file which has the date as MM/DD/YY in the 2nd column, and HH:MM:SS in the 3rd column.
I need to change the date format to YYYY-MM-DD and merge it with the the time HH:MM:SS. How will I got about this?

pwconv
pwconv(1M) System Administration Commands pwconv(1M)NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd
SYNOPSIS
pwconv
DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd.
pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
already in /etc/shadow and should not be modified.
If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates
/etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in
/etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated.
If the /etc/shadow file does exist, the following tasks will be performed:
Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.
Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.
Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre-
sponding entry in /etc/shadow.
The pwconv command can only be used by the super-user.
