Timezone Settings Error Loop

[dwcouch]

This error re-iterates endlessly:

Warning: strtotime() [function.strtotime]: 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/Chicago' for '-6.0/no DST' instead in C:\xampplite\htdocs\tumblr\thimble\parser\parser.php on line 486
