When does wtmp reset?

[Terence P. Ma]

UNIX-gurus:

While looking over the earlier question of how to look up when someone was
last logged in, I see that the command "last" (on my SS1+; SunOS4.1.1) is
appropriate.  However, whenever I type "last" I note that wtmp is started at
the same time as the earliest login of that particular day.  I am suspecting
that this is because I have the accounting program run in the middle of the
night and it resets wtmp (is this correct? -- couldn't find it in the any
manual entry).

I know that the last login date is in /var/adm/lastlog.  Is there an easy
way to get the lastlogin date and time of all users or groups of users
without using "finger -s user1 user2 ..." to get at it?

Thanks!
Tere
