$TimeUnit

$TimeUnit
gives the minimum time interval in seconds recorded on your computer system.

$TimeUnit determines the minimum granularity of measurement in functions like Timing and DateList.

In some functions the actual time granularity may be much smaller than $TimeUnit.

The timing granularity on this machine:

When a computation takes less than $TimeUnit seconds, repeat to get a better timing:
