After installing a php application my site loads the app with a warning overlayed on the page
Warning: 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.
I believe the problem is that there is no timezone set in php.ini on this server. My server company doesn't think that this is something they should have configured when they set up the server, so how do I edit the php.ini file and what do I insert to get rid of this error.
