    how can I use getdate(...) excluding TZ.


    Hi,

    My timezone is GMT +2
    So when I do a
    $date = getdate( 0 );

    I get:

    $date =
    {
    ['seconds'] (integer) = 0
    ['minutes'] (integer) = 0
    ['hours'] (integer) = 2 //<-- Hour is not 0 but +2
    ['mday'] (integer) = 1
    ['wday'] (integer) = 4
    ['mon'] (integer) = 1
    ['year'] (integer) = 1970
    ['yday'] (integer) = 0
    ['weekday'] (string) = "Thursday"
    ['month'] (string) = "January"
    ['0'] (integer) = 0
    }

    I cannot do:
    $date = getdate( 0 - (2*3600) );
    as negative numbers are not accepted, (on the window server).

    So how can I do getdate( 0 ) and return the value without it been
    converted by the server TZ.
    Using setlocal(...) is also a bit of a Hacky kind of way of doing
    things.

      getdate(time() - (2*3600)) perhaps?

          Timestamps don't have a time zone -- they're always in GMT. So, when
          you say a timestamp of zero, that's Jan 1, 1970 0:00 GMT -- which,
          because your GMT offset is +2, is really Jan 1, 1970 02:00 in your
          timezone.

          What is it that you're trying to accomplish? Do you want the
          timestamp for midnight on Jan 1, 1970 in /your/ timezone? Try this:

          strtotime('Jan 1 2007');

              strtotime('Jan 1 1970');

                  Yes that would work for the current time.

                  But as mentioned in my OP that will not work for 1/1/1970
                  you cannot do
                  >$date = getdate( 0 - (2*3600) );

                      My server is in the US with GMT+5 and I am working in GMT-2.
                      One is a *nix machine, the other a Windows.

                      I use a value of 0, (1/1/1970), to show that the date has not been
                      set.
                      The Unix Value is saved on the DB.
                      So when I do if( $date == 0) then ... I know that the date has not been
                      set.

                      mktime(...) as a GMT function but
                      getdate(...) does not.

                      And in my case I often use the two to set date ranges, (so if a user
                      registered on 1/1/1987 @ 12:33:20 I want to set the date on the DB as
                      1/1/1987 @ 00:00:00).

                      But because getdate(...) converts the dates sometimes it does not work
                      as expected.
                      For 1/1/1970 The date becomes 1/1/1969 19:00, (it works on the Unix
                      Box).
                      If the user registers between 0:00 and 05:00 they get access for the
                      day, (and sometimes the month before), because they pay by the day, I
                      don't want to cheat them.

                      So what I want is when I use getdate(0) I will get just that, the
                      1/1/1970 0:00:00, without having to worry about TZ.

                      At the end of the day I want to be assured that the date I passed to
                      getdate(...) is exactly the value that I passed, not a 'adjusted'
                      server time.

                      I hope I am making it a little clearer what I am using the dates for.

                          getdate(time() - (2*3600)) perhaps?

                          as negative numbers are not accepted, (on the window server).

                          Sorry. Wasn't reading carefully.

                          As there is no GMT version of getdate(), I think you'll need to obtain
                          each component of the date using gmdate().
