From 627067118c6674dd944df962d24cf386afcd4326 Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Mon, 7 Nov 2011 23:20:31 +0200 Subject: avutil: Add av_timegm as a public function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is useful, since the normal timegm function isn't a standard function (requiring _BSD_SOURCE or _SVID_SOURCE on glibc to be visible, and not available on e.g. windows). The widely available function mktime uses the local time zone, which requires ugly workarounds to handle UTC time.
