Maybe it is too tight. The solutions are:
1. Modify time limits to enough longer
2. Modify tests not to heavily rely on accuracy of the timer
I think it is not good to tweak the test parameter for the issue which
depends on the environment, so I guess the latter is better.
There're two tests which rely on the accuracy of the timer.
The intention of the tests is not to test asio::deadline_timer, to test
asiolink::Intervaltimer. In my opinion, the issue can be solved with the
=> Test if the call back function will be called after the
specified interval or longer instead of checking the elapsed
time is within +/- 50 msec.
=> Test if the return value of getInterval() will be updated after
calling setup() instead of measuring the time
Suggestions or advices to fix the issue are welcome.
