    Date string manipulation

    Forgive me. I am new to PHP and am a little confused by date
    manipulation and would appreciate some guidance.
    I have a string containing a date which has been parsed from and RSS
    feed. This looks something like: "Tue, 25 Mar 2008 04:28:18 -0500" and
    is stored in $rssdate

    I would like to manipulate this date to correct the timezone
    adjustment. (I happen to know that the item I am referencing was
    actually timestamped at 09:28:18). I suspect that I have to turn it
    into a timestamp (is that correct?)

    Attempts to use strtotime($rssd ate) have failed... and dropping the
    -0500 allows strtotime to complete, but it returns a date of 18 Mar
    (which is counter-intuitive, to say the least).

    Can anyone offer me any clues?

      i think you need strtotime:
      PHP: strtotime - Manual
      http://nl3.php.net/manual/en/function.strtotime.php
      Parse about any English textual datetime description into a Unix timestamp


      and strftime:
      PHP: strftime - Manual
      http://nl3.php.net/manual/en/function.strftime.php
      Format a local time/date according to locale settings

          What version of PHP are you using. Parsing the example date you provided
          with strtotime seems to work fine here with PHP 5.2.5.

              Why ignore the minutes? Yes, there do exist timezones where the minutes
              are not '00'.
