From: Christian Mauderer <christian.maude...@embedded-brains.de>
We currently don't have a timegm function. There seems to be no easy
way to replace this function with POSIX functions in a thread save
way. This patch just avoids the call.
Note that with this solution, the caching feature is effectively
disabled.
