From the man page, passwd(5):
name User's login name.
password User's encrypted password.
uid User's id.
gid User's login group id.
class User's general classification (unused).
change Password change time.
expire Account expiration time.
gecos General information about the user.
home_dir User's home directory.
shell User's login shell.
[..snip..]
The class field is currently unused. In the near future it will be a key
to a termcap(5) style database of user attributes.
The change field is the number in seconds, GMT, from the epoch, until the
password for the account must be changed. This field may be left empty
to turn off the password aging feature.
The expire field is the number in seconds, GMT, from the epoch, until the
account expires. This field may be left empty to turn off the account
aging feature.
I've no idea what 'from the epoch' means but since most specifications
of time in seconds are since 01 Jan 1970 00:00:00 I will guess that's
what it means. :)
Now, how to generate such values for your /etc/passwd, I dunno. I've
done it before, I had to write some (not very good) code to do it, gets
difficult when you have to take the various leap year rules into account.
