Integrate Smarty Template Parsing into CodeIgniter

[eluser]Abel A.[/eluser]
I get this error when smarty compiles a template:

Code:

A PHP Error was encountered

Severity: Warning

Message: strftime() [function.strftime]: 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/Los_Angeles' for 'PDT/-7.0/DST' instead

Filename: sysplugins/smarty_internal_templatecompilerbase.php

Line Number: 148

it's a fresh installation of CI w/ only your smarty plugin
