Problem with date and getting last month

    I've got a really weird problem that perhaps is more server related than PHP related, but well, I don't know.

    If I do the following in PHP:

    date("M")
    Code (markup):
    I get: Oct
    Which is correct.

    If I try to get the date from the previous month by using:

    date("M",strtotime("-1 month"))
    Code (markup):
    I get: Oct
    Which is not correct as I would like it to say Sep.

    date("Y-m-d")
date("Y-m-d",strtotime("-1 month"))
date("Y-m-d", mktime(0, 0, 0, date("m")-1, date("d"), date("Y")))
    Code (markup):
    Gives me:
    2011-10-31
    2011-10-01
    2011-10-01

    Can anyone figure out what's going on?

    (Date and hwclock on my server gives the same time as date();)

    strtotime("-1 month")
    it's decreasing 30 days in spite of 31 days which is creating the problem.

    But why does it do that? date("m")-1 does the same, which I find strange?
