From 48bd82a0033c52a6cbf706311df3ba4412771455 Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <lfleischer@calcurse.org>
Date: Mon, 10 Oct 2016 08:42:22 +0200
Subject: Refactor duration/end time parsing

Replace all remaining invocations of parse_time() by parse_datetime()
which now indicates whether a date was supplied or not.
