What are the best practices for handling time calculations and formatting in PHP and JavaScript?

When handling time calculations and formatting in PHP and JavaScript, it's important to use built-in functions and libraries to ensure accuracy and consistency. In PHP, the DateTime class provides powerful methods for working with dates and times, while in JavaScript, the Date object offers similar functionality. It's also crucial to consider timezones and formatting options to display time information correctly. 

// Example PHP code snippet for handling time calculations and formatting
