> Understanding the clicks data - train-item-views.csv

This query is specific to the file "train-item-views.csv".
The timeframe column is a bit misleading. The time column is NOT a timestamp which makes it difficult to figure out what is the true sequence if items within a session. I am assuming that the timeframe column tells us the time elapsed (in miliseconds) since the user first entered a search query on the retail platform till the moment the item was clicked.

Now my question is, should we sort each session in non-descending order of the timeframe? To get the correct sequence of items in a session? If yes then why isn't the datafile already sorted. If NOT, then what is meaning or use of the timeframe column?
