[nondet]time(:Goal)

Execute Goal, reporting statistics to the user. If Goal succeeds non-deterministically, retrying reports the statistics for providing the next answer.

Statistics are retrieved using thread_statistics/3 on the calling thread. Note that not all systems support thread-specific CPU time. Notable, this is lacking on MacOS X.

See also: - statistics/2 for obtaining statistics in your program and understanding the reported values.
- call_time/2, call_time/3 to obtain the timing in a dict.
bug: Inference statistics are often a few off.
