How can timezones impact the accuracy of converting Unix timestamps to normal time in PHP?

Timezones can impact the accuracy of converting Unix timestamps to normal time in PHP because Unix timestamps are typically stored in UTC time. When converting a Unix timestamp to normal time, it is important to set the correct timezone in PHP to ensure the conversion is accurate. This can be done by using the date_default_timezone_set() function in PHP. 

// Set the timezone to the desired timezone
date_default_timezone_set('America/New_York');

// Convert Unix timestamp to normal time
$timestamp = 1609459200; // Unix timestamp for January 1, 2021
$normal_time = date('Y-m-d H:i:s', $timestamp);

echo $normal_time; // Output: 2021-01-01 00:00:00
