MySQL 时间戳 - 为什么全为零?

2022-01-05 00:00:00 timestamp php mysql phpmyadmin

我正在使用 PHPMyAdmin,并且有一个名为时间戳"的 MySQL 表列.类型(惊喜!)是 TIMESTAMP,在属性"中我将它设置为 ON UPDATE CURRENT_TIMESTAMP.

I'm using PHPMyAdmin and I've got a MySQL table column called "timestamp." The type (surprise!) is TIMESTAMP, and in 'attributes' I've set it to ON UPDATE CURRENT_TIMESTAMP.

然而,每条新记录都有一个类似这样的时间戳:

However, each new record gets a timestamp that looks like this:

0000-00-00 00:00:00

我已经明确地将默认值设置为无,但是当我保存并返回查看时,它被设置为如上所示的全零.

I have explicitly set the default value to none, but when I save and come back to look, it is set to all zeros as above.

相关的 PHP 记录页面点击了这个查询:

The relevant PHP records page hits with this query:

$query = "INSERT INTO `pagehit` (user_id, pageurl)
VALUES ('" . $userid . "', '" . $pageurl . "')";

整个过程都在 XAMPP 下运行.

The whole thing is running under XAMPP.
