PHP strtotime return different value of Mysql UNIX_TIMESTAMP

I've searched post on stackoverflow,found some similar post.But I think this is a different one.

My PHP & Mysql server's timezone all set to "UTC".

In a table I use a timestamp field,value is "2010-11-08 02:54:15",I use sql like this:

SELECT id, 
       updated, 
       second( updated ) , 
       unix_timestamp( updated ) 
  FROM `transaction` 
 where id = 56

Got this:

id  updated              second  unix
-----------------------------------------开发者_运维技巧---
56  2010-11-08 02:54:15  15      1289184879 

Then I use this in php:

echo strtotime("2010-11-08 02:54:15");

Got this:

1289184855

The different is 24 seconds.

And I check these timestamps on http://www.unixtimestamp.com/index.php The php result is the correct one. So the mysql unix_timestamp function has bug? Mysql version is: 5.1.41

This is confirmed to be a bug that is fixed in 5.1.44.

See http://bugs.mysql.com/bug.php?id=51918 for details, the bug poster has found this issue exactly.

You will have no choice but to upgrade to avoid it by the looks of it.

I can't reproduce that in MySQL 5.1.41 on Linux. Perhaps this is Windows-only?
