Yes, on the cron line in which you want to use the date command, 
you must preceed it with a call to /etc/TIMEZONE.  Since /etc/TIMEZONE sets 
the environment parameter TZ, you have to invoke it with the 
shell "." command.  Example:

59 23 * * * pc=\%; . /etc/TIMEZONE;/bin/cp /etc/wtmp `/bin/date "+/usr/adm/wtmp/wtmp.${pc}y${pc}m${pc}d"`; /bin/cat /dev/null >/etc/wtmp

Is our entry for root which rolls out one days worth of /etc/wtmp data to
a file named "/usr/adm/wtmp/yymmdd" where yymmdd is 870401 for 
April 1, 1987.
