Example

In the place where you want to tick the start time you can use the following code:
Vars["Start"]=Now;
This will capture the current time & date within a global variable that I called it 'Start' (Can call it whatever you like).
Then, in the place you want to capture the end time & date, you should use the following code:
Vars["End"]=Now;
*Note: These code lines would be best written within start\end scripts.
TimeDiffDays(Vars["End"],Vars["Start"]);
