Personally, I've had a few software engineering jobs in the past and the distribution of requirements for time tracking is basically bimodal:

* A company is legally required to do time tracking. They usually have a shitty excel sheet to fill out (and every fills in the defaults), or at best a single "check in"/"check out" button that someone coded 10 years ago and still works.

* A company does time tracking to bill 7 different customers for the 12 different tickets each engineer is assigned. The software used to track this was made by 30 full-time engineers and requires a 200-page manual to administer. New employees have to take a 2h course to understand how to fill in their time sheet.
