TimeRemaining
gives the number of seconds remaining until the earliest enclosing TimeConstrained will request the current computation to stop.
Details

- If constrained by several nested TimeConstrained wrappers, TimeRemaining[] returns the time to the earliest time constraint.
- Without an enclosing TimeConstrained, TimeRemaining[] returns Infinity.
- TimeRemaining is accurate only down to a granularity of at least $TimeUnit seconds.
- TimeRemaining is based on absolute real time, not just CPU time.

Without an enclosing TimeConstrained, TimeRemaining[] returns Infinity:
TimeRemaining[] returns the time to the earliest time constraint:
After 2 seconds, there are 3 seconds remaining until the outer constraint of 5 seconds:
TimeRemaining is based on absolute time ("wall clock time"), as measured by AbsoluteTiming:
The CPU time taken by the operation can be measured using Timing, and it is smaller:
The presence of AbortProtect may invalidate the times reported by TimeRemaining[]:
