Win32 sendmail.c doesn't respect DST

Patch attached for this. Can someone validate my thinking, test and commit if possible?

Is it too late for 4.3.9?

Cheers,

John.

Subject: [PHP-DEV] Win32 sendmail.c doesn't respect DST

Hi,

(Long time lurker, first time poster).

Windows only 4.3.9rc2

sendmail.c sets the date header if you don't supply one, unfortunately it doesn't respect DST:

I'm in the UK in daylight savings time (i.e. GMT+1)

So the time is 09:50, i.e. 09:50 GMT +0100 (08:50 GMT)

The current mail header code gives 09:50 GMT +0000 which isn't right. The fix looks easy, change the code below:

zoneh /= (60 * 60);
zonem = (abs(_timezone) / 60) - (zoneh * 60);
to:
zoneh /= (60 * 60);
zonem = (abs(_timezone) / 60) - (zoneh * 60);
zoneh += tm->tm_isdst;

in the PostHeader function.

I'm waiting to be proved wrong in the most embarrassing way possible (particularly as the code has been like this for 8 years).

Thanks,

John.
