What steps can be taken to troubleshoot and resolve errors related to incorrect timestamp generation in PHP calendars?

The issue of incorrect timestamp generation in PHP calendars can be resolved by ensuring the correct timezone is set before generating timestamps. This can be done using the date_default_timezone_set() function in PHP.

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

// Generate a timestamp for the current date and time
$timestamp = time();

// Use the timestamp in your calendar application
echo date('Y-m-d H:i:s', $timestamp);
