From: phil at adigital dot com dot mx
Operating system: Win XP and Linux FC4
PHP version: 5.1.2
PHP Bug Type: Date/time related
Bug description: date() doesnt five right date sometimes
Description:
------------
date("Y-m-d H:i:s", 1175403600);
shows: 2007/4/1 00:00:00
Should be: 2007/3/1 23:00:00
the hour is shift 1 hour in PHP from march/11/2007 to april/1/2007 (20
days of 1 hour diff !)
The same problem repeat 2008, 2009, 2010, 2011, etc, but the beginning of
problem is +/- 5 days and ending problem too +/- 5 days
It seems the problem is not occuring before 3/1/2007
I thought first it was maybe a daylight savings problem
BUT:
- it happens on our redhat 8 servers in US (ev1), local servers (FC4) AND
windows XP
- the start and end date of the problem is quite random in a period ,
daylights are quite fixed
- It doesnt happen before 3/1/2007
SO i guess it's a bad bug somewhere
the result *must* be same as unix_timestamp C++ function no ?
It is not
Thx !
Reproduce code:
---------------
print date("Y-m-d H:i:s", 1175403600); // bad +1 hour
print date("Y-m-d H:i:s", 1238417200); // bad +1 hour
print mktime(0,0,0,4,1,2007);
Expected result:
----------------
2007/3/1 23:00:00
2009-03-30 06:46:40
1175407200
Actual result:
--------------
2007/4/1 00:00:00
2009-03-30 07:46:40
1175403600
