Server Time

[phpQuestioner]

Is there any way to get a server time from another server, other then your own. I keep having trouble with my server's time bouncing up and down in AOL. Any way to do this?

The only thing I can think of is to write a php script that will echo the current time and out it on the desired server.  Then fetch the url and read the output from the script.  It would be a little web service.

You could use php's socket functions to connect to port 13 of the server.

This might be linux rdate probem.

 

Anyway, There are NTP servers available. Use this code to query an NTP (Network Time Protocol) Server.

<?php 
function query_time_server ($timeserver, $socket) {
  $fp = fsockopen($timeserver,$socket,$err,$errstr,5);
        # parameters: server, socket, error code, error text, timeout
  if ($fp) {
    fputs($fp,"\n");
    $timevalue = fread($fp,49);
    fclose($fp); # close the connection
  }
  else {
    $timevalue = " ";
  }

  $ret = array();
  $ret[] = $timevalue;
  $ret[] = $err;     # error code
  $ret[] = $errstr;  # error text
  return($ret);

} 
?>

I keep having trouble with my server's time bouncing up and down in AOL.

 

I don't know what that means, but any time I see the name AOL I think of cache issues and proxy servers as the most likely causes of problems.  Does your 'bouncing up and down' problem appear when other people (using non-AOL services) view the pages?
