Description:
------------
Halloween, according to strtotime(), is both Sunday and Monday this year. I haven't checked other years, but I just ran into this.

Uh... that's all I've got for you.

Reproduce code:
---------------
echo("<p>");
echo(date("d_M_y",mktime(0,0,0,10,30,04)));
echo("</p><p>");
echo(date("d_M_y",strtotime("tuesday",mktime(0,0,0,10,30,04))));
echo("</p><p>");
echo(date("d_M_y",strtotime("monday",mktime(0,0,0,10,30,04))));
echo("</p><p>");
echo(date("d_M_y",strtotime("sunday",mktime(0,0,0,10,30,04))));
echo("</p>");

Expected result:
----------------
30_Oct_04

02_Nov_04

01_Nov_04

31_Oct_04

Actual result:
--------------
30_Oct_04

01_Nov_04

31_Oct_04

31_Oct_04

We are happy to tell you that you just discovered Daylight Savings
Time. For more information see:

Instead of using mktime/date consider using gmmktime and gmdate which do
not suffer from DST.
