Are there any best practices or recommendations for synchronizing server-side time with client-side time in PHP applications?

When synchronizing server-side time with client-side time in PHP applications, it is important to ensure that both times are accurately aligned to avoid discrepancies in time-sensitive operations. One common approach is to use JavaScript on the client-side to fetch the current time from the server and adjust it based on the client's timezone offset. This helps maintain consistency between the server and client times. 

// Server-side PHP code to send current server time to client
$serverTime = time(); // Get current server time
echo "<script>var serverTime = $serverTime;</script>"; // Send server time to client

// Client-side JavaScript code to adjust server time based on client's timezone offset
<script>
var clientTime = new Date().getTime(); // Get current client time
var serverTimeDifference = serverTime - clientTime; // Calculate time difference
var adjustedServerTime = new Date(clientTime + serverTimeDifference); // Adjust server time
</script>
