Get Time in php code

I am looking for a PHP developer who can help me get the time in a 12-hour clock format with AM/PM. I would like the time to be displayed dynamically based on the user's local timezone. Therefore, I need someone with experience in timezone support. The time should be displayed dynamically and not just retrieved one time. If you have any suggestions or ideas, please advise. Thank you! Ideal skills for this job include:
- PHP development experience
- Understanding of timezone support
- Ability to display time dynamically
- Knowledge of JavaScript (optional)
