evaluates expr, stopping after t seconds.
returns failexpr if the time constraint is not met.
- TimeConstrained generates an interrupt to abort the evaluation of expr if the evaluation is not completed within the specified time.
- TimeConstrained evaluates failexpr only if the evaluation is aborted.
- TimeConstrained returns $Aborted if the evaluation is aborted and no failexpr is specified.
- TimeConstrained is accurate only down to a granularity of at least $TimeUnit seconds.
- Aborts generated by TimeConstrained are treated just like those generated by Abort, and can thus be overruled by AbortProtect.
- TimeConstrained[expr,Infinity] imposes no time constraint.
- TimeConstrained may give different results on different occasions within a single session, for example as a result of different conditions of internal system caches.
- TimeConstrained takes account only of CPU time spent inside the main Wolfram Language kernel process; it does not include additional threads or processes.
