Description:
------------
This appears:
Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Paris' for '2.0/DST' instead in C:\xampp\htdocs\something.php on line 7
Distance between 2 dates is 3 days.
What I must do (write) that this message doesn't appear any more?

Test script:
---------------
<?php
$iStartDate = '2010-05-29';
$iEndDate = '2010-06-01';
printf
(
'Distance between 2 dates is %d days.',
(strtotime($iEndDate) - strtotime($iStartDate)) / 86400
);
?>

Expected result:
----------------
Distance between 2 dates is 3 days.
