Why is it recommended to work with timestamps in PHP when dealing with dates?

Working with timestamps in PHP when dealing with dates is recommended because timestamps are integer values that represent the number of seconds since the Unix Epoch (January 1, 1970). This makes them easier to compare, manipulate, and format than traditional date strings. By using timestamps, you can avoid common pitfalls such as timezone conversions, daylight saving time adjustments, and inconsistencies in date formats. 

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

// Convert a date string to a timestamp
$dateString = '2022-12-31';
$timestamp = strtotime($dateString);

// Format a timestamp as a date string
$formattedDate = date('Y-m-d', $timestamp);
