Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Denver' for 'MST/-7.0/no DST' instead in /home/student/ginsbura/public_html/astr3520_2008/tracker.php on line 3
