wait exactly x seconds please, need not be more than 2 seconds but must be accurate within say 50 milliseconds, your function must honestly output the amount of time it has actually waited and that will be tested against what it was supposed to do.

i think the best thing for this problem would be for you to do the timing in the test suite so that the player only needs to write the code to do the waiting. This will also prevent the user from just outputting the input argument.

You say that the function should return the time to within tol, yet you test for exact equality in the test suite? Why not test using the tol to conform to your description?

I succeeded in making this work in MATLAB, but I can't get it to work for the tests that occur here. From the solution map, it looks like others have the same frustration. Please follow the advice of bmtran and Fig, rewriting the problem so that the requirements are clear and there is not a problem with using tic in the function itself.

Currently the test for this problem demands accuracy to the nearest 1/10 millisecond. I see a number of solutions (including mine) resort to cheating to achieve this. I'm not sure whether it is currently possible to solve this problem without cheating.
