Calculate timing in X++ operations [WinAPI::getTickCount()]

While reading some lengthy operations e.g. reading data from CSV files, fetching data in query and uploading data etc I wanted to know the time consuming in each opertion. This helped me to optimize my logic or query in making client-server calls.
We can use following function to know about time consumption;

int                 startTime, endTime;

startTime = WinAPI::getTickCount();
[Perform X++ operations]

endTime = WinAPI::getTickCount();

info(strFmt('It took %1 minutes', ((endTime - startTime)/1000)/60));

Note: WinAPI::getTickCount() tells time in milliseconds you need to change accordingly as per your required unit.
