我在数据库中有一个存储日期的表，但是采用这种格式
2015-04-20 12:47:58
我需要回应这个时间但是-2小时，任何解决方案？我知道在db中使用timestamp会更容易，但我无法访问将日期插入其中的脚本。

使用INTERVAL：
SELECT date - INTERVAL 2 HOUR FROM yourtable
返回：2015-04-20 10:47:58
首先尝试这种方式看它是否有效，甚至不命名表或字段，只选择：
SELECT '2015-04-20 12:47:58' - INTERVAL 2 HOUR
给予：2015-04-20 10:47:58
在PHP中，您需要执行此查询：
$result = $db->query('SELECT eventTime - INTERVAL 2 HOUR AS newdate FROM hlstats_Events_Chat');
while($row = $result->fetch_assoc()){
echo $row['newdate'];
}
答案 1 :(得分：0)
使用DATE_SUB功能，您可以从日期时间字段值中减去时间间隔：
SELECT DATE_SUB(columnname, INTERVAL 2 HOUR) FROM tablename
答案 2 :(得分：0)
使用DateTime对象：
<?php
// Long version
$str = '2015-04-20 12:47:58'; // Your date
$dateTime = DateTime::createFromFormat('Y-m-d H:i:s', $str); // Conversion to DateTime object
$dateTime->sub(new DateInterval('PT2H')); // Substract 2 hours
$formatedDate = $dateTime->format('Y-m-d H:i:s'); // Formatting the new date
// Short version
$formatedDate = DateTime::createFromFormat('Y-m-d H:i:s', $str)->sub(new DateInterval('PT2H'))->format('Y-m-d H:i:s');
?>

使用INTERVAL或DATE_SUB
SELECT '2015-04-20 12:47:58' - INTERVAL 2 HOUR;
SELECT DATE_SUB('2015-04-20 12:47:58', INTERVAL 2 HOUR);

对我来说听起来像是时区问题？
您可以在查询之前使用mysql set time_zone = '-02:00';。
SELECT NOW();
SET time_zone = '-02:00';
SELECT NOW();
但是你可能想要在你的时区中获得时间，即你的数据库设置是-2小时。
$dbDate = '2015-04-20 12:47:58';
$dbTimezone = 'UTC'; // ?
$yourTimezone = 'Europe/Amsterdam'; // that's where i am (UTC +2)
$newDate = new DateTime($dbDate, new DateTimeZone($dbTimezone));
$newDate->setTimeZone(new DateTimeZone($yourTimezone));
echo $newDate->format('Y-m-d H:i:s'); // will echo UTC + 2 in this case..
