get_nanotime
(Package: microbenchmark) :
Return the current value of the platform timer.
The current value of the most accurate timer of the platform is returned. This can be used as a time stamp for logging or similar purposes. Please note that there is no common reference, that is, the timer value cannot be converted to a date and time value.

microbenchmark
(Package: microbenchmark) :
Sub-millisecond accurate timing of expression evaluation.
microbenchmark serves as a more accurate replacement of the often seen system.time(replicate(1000, expr)) expression. It tries hard to accurately measure only the time it takes to evaluate expr . To achieved this, the sub-millisecond (supposedly nanosecond) accurate timing functions most modern operating systems provide are used. Additionally all evaluations of the expressions are done in C code to minimize any overhead.

This function is currently experimental. Its main use is to judge the quality of the underlying timer implementation of the operating system. The function measures the overhead of timing a C function call rounds times and returns all non-zero timings observed. This can be used to judge the granularity and resolution of the timing subsystem.
