What are the potential pitfalls of calculating click intervals in PHP using timestamps?

One potential pitfall of calculating click intervals in PHP using timestamps is the risk of encountering timezone discrepancies. To solve this issue, it is important to ensure that all timestamps are in the same timezone before performing any calculations. 

// Set the default timezone to be used in the script
date_default_timezone_set('UTC');

// Get current timestamp
$currentTimestamp = time();

// Get timestamp of previous click
$previousTimestamp = strtotime('2022-01-01 12:00:00');

// Calculate the click interval in seconds
$clickInterval = $currentTimestamp - $previousTimestamp;

echo "Click interval: " . $clickInterval . " seconds";
