phphelp:
You need to set timezone explicitly in your php.ini (or in your code)php.ini , add this line:
date.timezone = "America/New_York"List of supported timezones is here.
I added this line to the php.ini and I got HTTP 500 error.

Convert MySQL Style Datecodes
This function is identical to PHPs date() function,
except that it allows date codes to be formatted using
the MySQL style, where each code letter is preceded
with a percent sign: %Y %m %d etc…
The benefit of doing dates this way is that you don’t
have to worry about escaping your text letters that
match the date codes.
