How does MySQL handle comparisons with timestamps in different time zones?

When comparing timestamps in different time zones in MySQL, it's important to ensure that the timestamps are converted to a common time zone before performing the comparison. This can be achieved by using the CONVERT_TZ function in MySQL to convert timestamps to a specific time zone before comparing them. 

// Assume $timestamp1 and $timestamp2 are timestamps in different time zones
// Convert both timestamps to a common time zone before comparing them
$query = "SELECT * FROM table WHERE CONVERT_TZ(timestamp_column, '+00:00', 'your_common_timezone') = CONVERT_TZ('$timestamp1', 'your_timestamp1_timezone', 'your_common_timezone') AND CONVERT_TZ(timestamp_column, '+00:00', 'your_common_timezone') = CONVERT_TZ('$timestamp2', 'your_timestamp2_timezone', 'your_common_timezone')";
$result = mysqli_query($connection, $query);
