multitime binary package in Ubuntu Oracular amd64

 Unix's time utility is a simple and often effective way of measuring
 how long a command takes to run ("wall time"). Unfortunately, running
 a command once can give misleading timings: the process may create a
 cache on its first execution, running faster subsequently; other
 processes may cause the command to be starved of CPU or IO time;
 etc. It is common to see people run time several times and take
 whichever values they feel most comfortable with. Inevitably, this
 causes problems.
 .
 multitime is, in essence, a simple extension to time which runs a
 command multiple times and prints the timing means, standard
 deviations, mins, medians, and maxes having done so. This can give a
 much better understanding of the command's performance.
