$months = date("n",time());
$years = date("Y",time());
$hours = date("G",time());
$mins = (date("i",time()));
$secs = date("s",time());
$mins = $mins-15;

To subtract 15 minutes from the current time, you can use strtotime():
要从当前时间减去 15 分钟，您可以使用strtotime()：
$newTime = strtotime('-15 minutes');
echo date('Y-m-d H:i:s', $newTime);

Change the date into a timestamp (in seconds) then minus 15 minutes (in seconds) and then convert back to a date:
将日期更改为时间戳（以秒为单位），然后减去 15 分钟（以秒为单位），然后再转换回日期：
$date = date("Y-m-d H:i:s");
$time = strtotime($date);
$time = $time - (15 * 60);
$date = date("Y-m-d H:i:s", $time);

You can use DateInterval
您可以使用 DateInterval
$date = new DateTime();
$interval = new DateInterval("PT15M");
$interval->invert = 1;
$date->add($interval);
echo $date->format("c") . "\n";

you can try this as well,
你也可以试试这个
$dateTimeMinutesAgo = new DateTime("15 minutes ago");
$dateTimeMinutesAgo = $dateTimeMinutesAgo->format("Y-m-d H:i:s");

How about substracting the 15 minutes from time() before converting it?
在转换之前从 time() 中减去 15 分钟怎么样？
$time = time() - (15 * 60);
And then use $time instead of time() in your code.
然后在代码中使用 $time 而不是 time() 。

Following is the way you can add days / hours / minutes / sec to current time
以下是您可以将天/小时/分钟/秒添加到当前时间的方法
$addInterval = date('Y-m-d H:i:s', strtotime("+$days days $hours hours $minute minute $sec second", strtotime(currentTime)));

Try using
尝试使用
$min = time() - 900; //900 seconds = 15 minutes

You can also use DateInterval object
您还可以使用 DateInterval 对象
<?php
$date = new DateTime('Y-m-d H:i:s');
$date->sub(new DateInterval('PT10H30S'));
echo $date->format('Y-m-d H:i:s');?>

To subtract 15 minutes you can do:
要减去 15 分钟，您可以执行以下操作：
date('Y-m-d H:i:s', (time() - 60 * 15));
You can replace 15 with the number of minutes you want.
您可以将 15 替换为所需的分钟数。
In case you're looking to subtract seconds you can simply do:
如果您想减去秒数，您可以简单地执行以下操作：
date('Y-m-d H:i:s', (time() - 10));
In this way you'll subtract 10 seconds.
通过这种方式，您将减去 10 秒。
