chrono::process_cpu_clock time points wrong by factor 1000 on Linux

Reported by: Markus Friedrich <friedrich.at.gc@…> Owned by: viboes
Milestone: Boost 1.56.0 Component: chrono
Version: Boost Development Trunk Severity: Problem
Keywords: Cc:

Description

The time point returned by boost::chrono::process_cpu_clock::now() is on Linux by a factor of 1000 to large. Measuring the duration between a sleep of e.g. 1 second returns

{1000000000000;0;0} nanoseconds

All other process clocks (process_real_cpu_clock, process_user_cpu_clock, process_system_cpu_clock) are fine!

Test program and patch attached.
