time(:Goal) is nondet

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

Note that is no portable way to get thread-specific CPU time. SWI-Prolog has implementations for Linux, Windows and MacOS. The automatic detection may work on some other operating systems.

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.
