I never met a lawyer who loved to docket their time, but I have met a number of lawyers (myself included) who were very good at it. I met many, many more lawyers who were not so good at it.
Maybe someday we will be completely rid of the billable hour, but even if that comes to pass, it will still be important for lawyers to be able to analyze how they are spending their time, if only to understand how to set fixed fees.
So, there we are. We all hate docketing. We all need to be good at it. Here it is. Fully explained. In small words. At last.
