Calculate the compilation time
 

I have a step for a C# solution compilation.I would like to write in log the time in seconds passed during the step execution.It is easy to write "Step started at ...,ended at ..." -but how can I write now many seconds passed between start and end?
I look at some VBScript Date\Time fctions here :

but I didn't see anything interesting.

Thanks for answer!
But maybe I was not clear,sorry!
I do not need to pause the build for some amount of time.
I just need to know exactly the duration of execution for some step-in seconds.
My idea was to create 2 macro-TIME_START and TIME_END,to set the value of TIME_START right before starting my step,end the value of TIME_END after ending my step.
Then based on values of these 2 macros to calculate the step time in seconds.
But I do not know how to do it.
Or maybe there is another way to get directly the execution step time...

The Wait step was just an example. Replace that with whatever type of step you want to time, using the script event code that is demonstrated.

Sorry,I did not notice the code behind!
It is exactly what I need-thank you very much!!
