Depends on the format they're in now.
If it's long and contained in something like Excel or a Word table, it's easiest to bring in the stuff directly from Excel, importing just the rows and columns you need. Then format to your liking. See help "import excel" or "importing tables from other applications" for more info.
If the list is short and not in a table like format now, it's easiest to forget the columns and make a table. That can keep everything better aligned. If the list is long, this can make a lot of copying-pasting.
Another trick is to make something like 4 text boxes, aligned next to each other. It's' easiest to create one box, set to the text frame options you want, and then clone that 3 times so they all have the same setup. Then paste the Date into the first, time in the next, etc. Then align and space as desired. Again, more work that just bringing in tabular data from another app.
Trying to do this with columns is not the best idea because, everything you add something to one column, it can force the stuff in the next column down. If you do want to do this, populate the first column, then the second, etc. Then you can choose text frame options. Doing it like that will not force the stuff in subsequent columns down.
