[PATCH 2/2] wininet: Use InternetTimeToSystemTimeW() to convert header values.

[Hans Leidekker]

From: Hans Leidekker

The current code calls mktime() which interprets its argument as local time while these
values are assumed to be in UTC.

[PATCH 2/2] wininet: Use InternetTimeToSystemTimeW() to convert header values.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=149676

Your paranoid android.
