From 0f4e25c5d7c031201fa7ad384cd9562b9c9c6004 Mon Sep 17 00:00:00 2001
From: Petr Tesarik <ptesarik@suse.com>
Date: Wed, 20 Jun 2018 11:50:18 +0200
Subject: [PATCH 1/2] [PATCH 1/2] Use monotonic clock to calculate ETA and
stats
Execution time should be always measured by a monotonic clock,
because the system clock may be affected by discontinuous jumps,
e.g. when time is set manually by an admin.
