test: bench_misc: short and long time stamps

Time stamp value may affect result of some test cases.
Also, test results are more consistent with fixed time
stamp values than currrent time (changes between test
runs). Added short (1 msec) and long (10 sec) time stamps,
and use those in short/long time_to_nsec test cases.
