 New Comment:

Since you're in the UK, and your computer/server is hence probably set
to Europe/London as a time zone, this is likely due to daylight saving
time.

For example, with 2010-04-01, strtotime() will be returning 12:00 am on
the 1st of April in your local time zone, but as the UK is now GMT+1,
gmdate() interprets that as being 11:00 pm on the previous day (which it
is in GMT), hence you get the result of 31-03-2010.

Description:
------------
Hi all 
I must be missing the plot, I have just noticed that when accessing date
information from a MYSQL DB, which has been stored in the format
yyyy-mm-dd, the date is being displayed incorrectly as of 29/03/2010.
Any date displayed using gmdate from and including 29/03/2010 and upto
04/04/2010, possibly further, is being displayed as the stored date LESS
1 day.

Example 
DB table shows 2010-03-30

echo gmdate("d-m-Y", strtotime("$test1")); interpretates the same
information as 29-03-2010.

Am I missing the point or is there something wrong?

Regards
Ross

Test script:
---------------
<?
$test26="2010-03-26";
$test27="2010-03-27";
$test28="2010-03-28";
$test29="2010-03-29";
$test30="2010-03-30";
$test31="2010-03-31";
$test32="2010-04-01";
$test33="2010-04-02";
echo gmdate("d-m-Y", strtotime("$test26")),"  = $test26<br>";
echo gmdate("d-m-Y", strtotime("$test27")),"  = $test27<br>";
echo gmdate("d-m-Y", strtotime("$test28")),"  = $test28<br>";
echo gmdate("d-m-Y", strtotime("$test29")),"  = $test29<br>";
echo gmdate("d-m-Y", strtotime("$test30")),"  = $test30<br>";
echo gmdate("d-m-Y", strtotime("$test31")),"  = $test31<br>";
echo gmdate("d-m-Y", strtotime("$test32")),"  = $test32<br>";
echo gmdate("d-m-Y", strtotime("$test33")),"  = $test33<br>";
?>

Expected result:
----------------
26-03-2010 = 2010-03-26
27-03-2010 = 2010-03-27
28-03-2010 = 2010-03-28
29-03-2010 = 2010-03-29
30-03-2010 = 2010-03-30
31-03-2010 = 2010-03-31
01-03-2010 = 2010-04-01
02-04-2010 = 2010-04-02


Actual result:
--------------
26-03-2010 = 2010-03-26
27-03-2010 = 2010-03-27
28-03-2010 = 2010-03-28
28-03-2010 = 2010-03-29
29-03-2010 = 2010-03-30
30-03-2010 = 2010-03-31
31-03-2010 = 2010-04-01
01-04-2010 = 2010-04-02
