Php – Stop Warning: date() [function.date]: from localhost

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 …………

There are many web applications that spring up this particular error. I could set

date_default_timezone_set('America/Los_Angeles');

But that is not the solution I am looking for.

Can I do something from system level. It happens only on LOCALHOST not on the actual production server.

Default set in php.ini is date.timezone = America/Los_Angeles

[update] edited php.ini
