在mysql数据库中存储日期和时间的最准确方法

Question

What is the best way to store date and time in the database? I tried using now() on localhost: it works, but on live server it counts far back as 8 hours ago and current timestamp does the same thing. What is the most accurate approach?

$d="INSERT INTO `users`(`time`) VALUES (now())";

Answer 1

You are storing the time in the most accurate method. It might not be in the correct timezone, but it is (as far as the server can tell) exactly that time when saved. If the timezone is incorrect, you will have to tell MySQL which timezone is considered "local" by executing something like SET time_zone = 'YOUR_TIME_ZONE' as soon as you open the connection.

A good trick to help with dealing with times is to make your storage layer only deal with times in UTC, and translate it to the local timezone in the presentation layer.

Answer 2

The only thing that you had wrong was your time zone

For example, use this :

SET time_zone = 'America/New_York';

with your time zone
