PHP upgrade caused error in PP 6.02

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/New_York' for 'EDT/-4.0/DST' instead in /home/rmresto/public_html/restoration_photos/adm-misc.php on line 1230

Is there a work around which will allow me to keep the current version, or do I have to upgrade the PP version?

You would need to upgrade your gallery. It is not recommented to use such an old version of Photopost with newer PHP.
