Squirrel Mail Time Zone Errors

[Chris Maness]

Is anyone getting these errors when logging in to Squirrel Mail?

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/Los_Angeles' for 'PDT/-7.0/DST' instead in
/usr/local/www/squirrelmail/functions/date.php  on line 428
