Date Warning After Upgrade Dolphin 7.0.8 to 7.0.9

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/Chicago' for 'CST/-6.0/no DST' instead in /home/expresat/public_html/inc/utils.inc.php on line 76

Does any one has a clue of how can I fix that?

Thanks in advanced.

You need to set the date/time zone in your master php.ini.  Put this line it it somewhere:

date.timezone = "America/Chicago"

Unless that isn't close to where you are.. if that's the case you can find the accepted combo here:

Many thnks for the advice.

Everything is working now!
