# From a date Object:
date_format ( DateTimeInterface $object , string $format )

# From the current time
$dateTime = new \DateTime(); 
// or pass a string or int ->`DateTime($date_time)`
$dateTime->format('y-j-d H:i:s T'); #print ex: 21-2-02 16:00:01 PST

# Or a quick one-liner:
date('g:i A m-d-Y', strtotime($date_time)); #print ex: 2:00 PM 02-02-2021
