$now _time = Date ("H:i:s"); Get the question about time, ask the seniors

$now _time = Date ("H:i:s"); Get the time question, ask the seniors
$now _time = Date ("H:i:s"); Will the current time obtained be 12 o'clock? Where do you want to set up a 24-hour system?
Because
$now _time = Date ("H:i:s"), for example 15:50:22
$s _time = "09:00:00";
$a = Strtotime ($now _time);
$b = Strtotime ($s _time);
Echo out a <>
