php not handling my timestamps well :(

[skrumpy]

I'm a complete neophyte when it come to coding. But I figured I would ask here since it is where the php experts hang out.

I've deduced that some php code is not handling the timestamps from my mobile phone in a proper fashion.

I use a Samsung D600 to email in my updates to my blog. All my posts show up on WordPress, but after having gone through the wp-mail.php all the timestamps are wrong.

They are 12 days, and some hours ahead of when they should be.

My phone's timestamp looks like this (I think)

Thu, 05 Oct 2006 18:01:42 -0500

Here is what it goes through

		if (preg_match('/Date: /i', $line)) { // of the form '20 Mar 2002 20:32:37'
			$ddate = trim($line);
			$ddate = str_replace('Date: ', '', $ddate);
			if (strpos($ddate, ',')) {
				$ddate = trim(substr($ddate, strpos($ddate, ',')+1, strlen($ddate)));
			}
			$date_arr = explode(' ', $ddate);
			$date_time = explode(':', $date_arr[3]);

			$ddate_H = $date_time[0];
			$ddate_i = $date_time[1];
			$ddate_s = $date_time[2];

			$ddate_m = $date_arr[1];
			$ddate_d = $date_arr[0];
			$ddate_Y = $date_arr[2];
			for ($j=0; $j<12; $j++) {
				if ($ddate_m == $dmonths[$j]) {
					$ddate_m = $j+1;
				}
			}

			$time_zn = intval($date_arr[4]) * 36;
			$ddate_U = gmmktime($ddate_H, $ddate_i, $ddate_s, $ddate_m, $ddate_d, $ddate_Y);
			$ddate_U = $ddate_U - $time_zn;
			$post_date = gmdate('Y-m-d H:i:s', $ddate_U + $time_difference);
			$post_date_gmt = gmdate('Y-m-d H:i:s', $ddate_U);
		}

After having gone through that, it always comes out 12 days ahead, and thus frustrates me. The only reason to have a mobile blog is to have instant updates.

Any ideas on how to fix this?

I'm quite sure this is caused by this line:

$time_zn = intval($date_arr[4]) * 36;

I don't event understand what you are trying to do here.

Or this one:

$post_date = gmdate('Y-m-d H:i:s', $ddate_U + $time_difference);

Because I don't know what the value of $time_difference is or where it comes from.

Also, if you look in to preg_match() you could shorten your code considerably.

Using [man]strtotime[/man] might help with some of the parsing.

echo gmdate('Y-m-d h:i:s', strtotime('Thu, 05 Oct 2006 18:01:42 -0500'));

outputs

2006-10-05 11:01:42

Which is the given time in UTC.
