I have events stored in the MySQL datebase with start date and time stored in column 'startTimeStamp' in UNIX format.

When I try to get events for particular date using simple query

SELECT * FROM events WHERE FROM_UNIXTIME(startTimeStamp, '%Y-%m-%d') = '2013-08-20'

everything works fine when date and time under timestamp is bigger then 2AM (i.e. 2013-08-20 03:00:00) but when it's earlier it's not displaying in same day.

Quick example: I have two events - same date but different time

  1. 2013-08-20 03:00:00 (1376960400)
  2. 2013-08-20 00:00:00 (1376949600)

I will get the first one when I run query mentioned before, but not the second one. To get the second one I have to query for events from day earlier (2013-08-19)

Do you have any idea why? Maybe I'm missing something?

Thanks a lot!

看看你的时区是什么：

SELECT @@global.time_zone, @@session.time_zone;

然后正确设置：

SET time_zone = timezonename;

这基本上是因为 Unix 时间戳的含义。这只是从 1-1-1970 的秒数，所以从技术上讲，1376949600 的值可能仍然是前一天，这取决于您的时区。

就我而言：

echo date("d-m-Y h:i", 1376949600);
// output: 19-08-2013 11:00

我想你可能选择了一个夏令时适用的地方。在这种情况下，时间转移主要是在凌晨 2 点到 3 点之间完成，这可能会导致不同的日子。

像这样使用：

$d="1376960400";
echo date("Y-m-d",$d);
