Just noticed, the seconds get dropped at the beginning of DST.

(Sorry, meant to say "difference between MARCH 31 and the first 10 days
of April")

Description:
------------
I tripped across this bug calculating the number of days between two
dates. It seems like something goes screwy in April and 0.041666667
seconds get dropped. The code below checks the difference in days
between May 31 and the first 10 days of April.
Reproduce code:
---------------
for ($iyear=2000;$iyear<= 2006;$iyear++) {
$s_st=$iyear."-03-31";
$st=strtotime($s_st);
for ($i=1;$i<=10;$i++) {
$addsecs=$st + ($i * 60 * 60 * 24);
$end = st + $addsecs;
$s_end=Date("Y-m-d",$end);
$end = strtotime($s_end);
$idiff = ($end - $st) / (60 * 60 * 24);
echo("Start: $s_st End: $s_end Diff: $idiff<br>");
}
echo("<hr>");
}
Expected result:
----------------
I would expect to see the number of days between the dates in question
Actual result:
--------------
Here's the results for just for 2006
Start: 2006-03-31 End: 2006-04-01 Diff: 1
Start: 2006-03-31 End: 2006-04-02 Diff: 2
Start: 2006-03-31 End: 2006-04-03 Diff: 2.9583333333333
