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/public_html/***.php on line ***
And i solved it by adding php.ini file into website root folder. Like /public_html/php.ini
Add new line into php.ini file:
date.timezone = "America/New_York"
save file and you should be ok now..
