下面的查询返回当前会话的时区。

select timediff(now(),convert_tz(now(),@@session.time_zone,'+00:00'));

查看MySQL服务器时区支持和system_time_zone系统变量。这有用吗?

尝试使用以下代码:

//ASP CLASSIC
Set dbdate = Server.CreateObject("ADODB.Recordset")
dbdate.ActiveConnection = MM_connection
dbdate.Source = "SELECT NOW() AS currentserverdate "
dbdate.Open()
currentdate = dbdate.Fields("currentserverdate").Value
response.Write("Server Time is "&currentdate)
dbdate.Close()
Set dbdate = Nothing

Use LPAD(TIME_FORMAT(TIMEDIFF(NOW(), UTC_TIMESTAMP),’%H:%i’),6,’+') to get a value in MySQL's timezone format that you can conveniently use with CONVERT_TZ(). Note that the timezone offset you get is only valid at the moment in time where the expression is evaluated since the offset may change over time if you have daylight savings time. Yet the expression is useful together with NOW() to store the offset with the local time, which disambiguates what NOW() yields. (In DST timezones, NOW() jumps back one hour once a year, thus has some duplicate values for distinct points in time).

这不是对这个问题的直接回答，但这篇博客文章提供了关于这个主题的有价值的信息:

引用博客文章:

在MySQL5+中，TIMESTAMP值是从会话时区转换而来的 存储从UTC到会话时区 检索。但是DATETIME不做任何转换。

将一个虚拟记录插入到具有时间戳的数据库中 选择该记录并获取时间戳的值。 删除该记录。获取服务器写入数据时使用的时区，忽略PHP时区。
