What are common pitfalls when working with timestamps in PHP?

One common pitfall when working with timestamps in PHP is not considering timezones. It's important to always set the timezone explicitly to avoid unexpected results when working with timestamps. To solve this issue, you can use the `date_default_timezone_set()` function to set the timezone to the desired value before working with timestamps. 

// Set the timezone to UTC
date_default_timezone_set('UTC');

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

// Display the current timestamp
echo $currentTimestamp;
