There are differences between the two methods of obtaining timestamps in PHP. Why?

Question

Try to use two methods of php to obtain the current timestamp. There are differences, but the two timestamps are converted into time at the same time point. I checked the unit of the timestamp on the network is seconds. Why is this happening?

---

$currentDay = getdate();
//var_dump($currentDay);
//2.1 获取当前的日期
//echo $currentDay["year"]."-".$currentDay["mon"]."-".$currentDay["mday"]."<br/>";
echo "时间戳为1:".strtotime(date("Y-m-d h:m:s"))."<br/>";
echo "时间戳为2:".$currentDay[0]."<br/>";
$time1 = strtotime(date("Y-m-d h:m:s"));
echo "不同的时间为:".date("Y-m-d H:m:s a",$currentDay[0])."--".date("Y-m-d H:m:s a",$time1);

The output result is:
The timestamp is 1:1492131843
The timestamp is 2:1492134903
The different times are: 2017-04-14 09:04:03 am--2017-04- 14 09:04:03 am
