Unhappy Time/Iteration and Time to Convergence FLUENT

I am working with ANSYS FLUENT and am trying to figure out the time per iteration for my solution. Does anyone know where I can find that information?

I see in the printout that there is a column titled time/iter. Is this the time per iteration? if so it doesnt make sense because I get a read out of something linke 00:22:48. I am assuming this is in hh:mm:ss format and I am doing 2D with only 55k elements so my iterations do not take 22 minutes each. Alternatively I was wondering if it might be time remaining and number of iterations remaining. Does anyone know if this is the case?

I really would just like to know how long the solution takes, the time per iteration and, if it is possible, the total memory used. Does anyone know how to do this?

Any help is greatly appreciated.

The printout is the estimated time needed to complete the remaining iterations (time remaining & iterations remaining).

Thank you LuckyTran. Do you if I can print the actual time for the solution to converge and how much memory was used for the selected solution settings?

The wall-clock time and CPU time can be found via Parallel > Timer > Usage. The memory usage can be found via Mesh > Info > Memory Usage.
