we've started to use CTest for our test running and it's generally
However, we sometimes get some odd timeouts in tests, and as such it has
been noticed that ctest doesn't use monotonic test timers, but instead
relies on gettimeofday().
When running on some of our devices, they start up thinking that it is
the year 2000 but during the test run, NTP kicks in, and fast forwards
the time to be 2017.
Using gettimeofday(), a test running during this NTP operation would
seem to have taken 17 years.
To avoid this, it's possible to use monotonic timers instead using
Is there any reason to not use this?
I've raised a bug* with a proposed patch.
Thanks in advance,
