I was asked how to get to SSIS log to see how much time took for the package to run.
Well, that depends.
On Development:When developing new package, after running the process (click on the green arrow or press F5) there's a new tab called Progress. Clicking it will show you everything about the package's execution, including the time it started and the time it finished.
On Production:When developing the package, open the SSIS menu (Yes, there is a menu called as the product's name. Microsoft...) and click on Logging... There, you can define logs for your package. You can log in many ways: Writing to SQL sever, output file, XML file and more. I recommend logging into SQL server and logging only the big and "hard" parts in your data flow. In the Details tab, pick up only the exceptional events, such as onError, onTaskFailed and onWarning. If you wish to know how much time took for you package to run, also pick up onProgress.
