I have a file that gets the local time (not GMT) $timestamp=time(); $seconds = 6*60*60; $timestamp-=$seconds; $tz = "CST"; $localtime= date("m/d/Y H:i:s",$timestamp); $localdate = substr($localtime,0,10); $localtime = substr($localtime,11,8); Currently I have the code above in about 13 files and wondering how to have this one file and then in the 13 files to go to this file to do the date/time conversion I am wondering how to call this file to do this from within these 13 php files Any assistance would be appreciated Thanks Ken
