No they don't have  this  you have to enter the data before , you do the second task , but they don't have to happen at the same time.
OK.
So it 's  it 's just I have a file whi which has this information on it , and then when you start using my scripts , for extracting the times , it adds the times at the bottom of the file. And so , um , I mean , it 's easy to create the files and leave them blank , and so actually we could do it in either order.
Oh , OK.
