PHP date('Y') generates Error?

I use a very simple snippet in my footer... says something like "Copyright 2008" by utilizing the PHP date function: echo date(’Y’);

I keep getting this error in my logs:
It is not safe to rely on the system’s timezone settings. Please use the date.timezone setting, the TZ environment variable 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 ’CDT/-5.0/DST’ instead

But I can’t find the MODx documentation on how to use its API to avoid the use of my simple script.

Can anyone point me in the right direction? Thanks thanks thanks.

Ah... found this:

$rnStrFormat = ’%B %d, %Y, %H:%S’;
$rnStrToday = strftime($rnStrFormat); // März 23, 2006, 13:23

On the page http://wiki.modxcms.com/index.php/Creating_Snippets

That seems to eliminate the error.

Interesting. According to the PHP documentation, they should both generate the same warning.

Errors/Exceptions

Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT message if using the system settings or the TZ environment variable. See also date_default_timezone_set()

Ah... right. I was thinking this was a MODx error... it’s a Linux message.

I think I should try setting the environment on the bash command line:

Actually it’s a PHP error, and only since version 5.something-or-another.

When I run across this, I add the proper setting to my config.inc.php file. You can set it in your php.ini file if you have access to it, or use the .htaccess file.
