<?php $currentDate = date("Y-m-d"); $currentTime = date("H:i:s"); $currentDateHour = date("H", strtotime($currentDate . $currentTime)); // This is the date I'm pulling from the database, it only displays // when in strtotime for some reason. It displays accurately to what is in the mySQL DB $upDate = date("Y-m-d H", strtotime($row2[post_date])); // Some variables to make life easier for later if statements if I ever get that far. Displays accurately. $upDatehour = date("H", strtotime($row2[post_date])); // trying simple subtraction $hour = $currentDateHour - $upDatehour; // this is where the result is incorrect, what is wrong here? Any method I've tried gives me the same result, with or without strotime.. it's gotta be something simple, always is! print $hour;
