This sample code can be used to display visitor's local time based on their IP address using PHP programming languages and IP2Location BIN database. Free database is provided by IP2Location LITE at http://lite.ip2location.com/ 
  1. <?php
  2. error_reporting(E_ALL);
  3. ini_set('display_errors', 1);
  4. set_time_limit(0);
  5.  
  6. require_once('IP2Location.php');
  7. $loc = new IP2Location('databases/DB24-SAMPLE.BIN', IP2Location::FILE_IO);
  8.  
  9. //$loc = new IP2Location('databases/IP-COUNTRY-SAMPLE.BIN', IP2Location::SHARED_MEMORY);
  10.  
  11. //$loc = new IP2Location(ROOT . 'databases/IP-COUNTRY-SAMPLE.BIN', IP2Location::MEMORY_CACHE);
  12.  
  13. $ip = $_SERVER['REMOTE_ADDR'];
  14.  
  15. $utc_time = gmdate("H:i:s");
  16. $utc_h = explode(':', $utc_time);
  17. $time_zone = $loc->lookup($ip, IP2Location::TIME_ZONE);
  18. $country_code = $loc->lookup($ip, IP2Location::COUNTRY_CODE);
  19. if (strcmp($time_zone, "-") == 0) {
  20. 	$localdate = $utc_time;
  21. }
  22. else {
  23. 	$time = explode(':', $time_zone);
  24.  
  25. 	if ($utc_h[0] + $time[0] < 0) {
  26. 		$hour = $utc_h[0] + 24 + $time[0];
  27. 	}
  28. 	elseif ($utc_h[0] + $time[0] >= 24) {
  29. 		$hour = $utc_h[0] + $time[0] - 24;
  30. 	}
  31. 	else {
  32. 		$hour = $utc_h[0] + $time[0];
  33. 	}
  34.  
  35. 	$localdate = $hour . gmdate(":i:s");	
  36. }
  37.  
  38. date_default_timezone_set("Asia/Kuala_Lumpur");
  39. $date = date_create($localdate);
  40. echo 'Country Code: ' . $country_code . '<br>';
  41. echo 'Local Time: ' . date_format($date, "H:i:s") . ' (' . $time_zone . '). <br>';
  42. echo 'Server Time: ' . strftime("%H:%M:%S (%z)") . '<br>';
  43. echo 'UTC Time: ' . gmdate("H:i:s (e)") . '<br>';
  44. ?>
