php quot time

$now_time = date("h:i:s"); 获取时间的问题,请教前辈
$now_time = date("h:i:s"); 获取到的当前时间会不会是12时制的?要在哪儿设置成24小时制的?
因为
$now_time = date("h:i:s");比如15:50:22
$s_time = "09:00:00";时,
$a = strtotime($now_time);
$b = strtotime($s_time);
echo 出 a

------解决方案--------------------
小写h为12小时格式,大写为24小时格式。

------解决方案--------------------
h本来就是12小时制的啊,H是24小时的
