Last Visited Time in Getinfo profile?

No... He just beat me to it.

Do something like this.

if ($userinfo[invisible]) {
  $lastvisit = "N/A";
} else {
   $user_lasttime = vbdate($timeformat,$userinfo[lastactivity]);
   $user_lastdate = vbdate($dateformat,$userinfo[lastactivity]);
   $lastvisit = $user_lastdate . "at". $user_lasttime;
}

Then put $lastvisit in your template.
