Summary: curl_getdate(), DST, and cookie expiration

Initial Comment:
Platform: Windows XP
libcurl: 7.14

With the system clock properly configured to
automatically adjust for Daylight Saving Time,
curl_getdate() appears to return a time_t value which
is 1 hour ahead of the correct value. This prevents
cookies from expiring at the proper time.

The following demonstrates the problem:

#include <stdio.h>
#include "curl/curl.h"

int main()
{
        time_t tNow = ::time(NULL);
        tm tmGMT;
        char szGMT[128];

        ::memcpy(&tmGMT, ::gmtime(&tNow), sizeof(tm));
        ::strftime( szGMT, 128, "%a, %d-%b-%Y %H:%M:%S GMT",
&tmGMT );

        time_t tCURL = ::curl_getdate(szGMT, NULL);
        time_t tDiff = tCURL - tNow;

        printf("Current time: %s\n", szGMT);
        printf("Sytem time_t: %i\n", tNow);
        printf("libcurl time_t: %i\n", tCURL);
        printf("Difference: %i seconds\n", tCURL - tNow);

        return 0;
}

-----------------------------------------------------------
Example run with properly configured system clock
(during DST):

Current time: Thu, 30-Jun-2005 03:02:14 GMT
Sytem time_t: 1120100534
libcurl time_t: 1120104134
Difference: 3600 seconds

-----------------------------------------------------------
Example run with automatic DST adjustment disabled:

Current time: Thu, 30-Jun-2005 03:02:28 GMT
Sytem time_t: 1120100548
libcurl time_t: 1120100548
Difference: 0 seconds
