$TimeUnit

$TimeUnit

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

Details

  • Typical values for $TimeUnit are 1/100 and 1/1000.
  • $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.

Examples

The timing granularity on this machine:

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

Divide by the number of repetitions to get the average timing:

You may want to time just a part of the computation:
