Earlier quoted context omitted.
For project budget and billing purposes, it is sufficient to track the number of hours each day. This court decision, however, would require to also track the start and end time, as well as the durations of all breaks. That's because there are laws regulating how much break time you have to take each day (dependend on how many hours you work) and also how much time has to pass between two work days. If you're working…
No idea why you're so bitter about this, but obviously there is no expectation that each minute is recorded. This just spreads a common practice to the exploitative employers that don't respect workers rights - such as the right to have a20 minute break during the day.
Bingo! In practice, employees will just fill in whatever values are convenient. Nothing's going to change for an employee who was pressured (explicitly or implicitly) to work unpaid overtime – now they'll be pressured (explicitly or implicitly) to not track the time they're working after hours. It's just more bureaucracy for everyone, including for honest, fair employers.
And yes, I'm very bitter about this. Bureaucratic, ivory-tower decisions like this one are partly responsible for phenomenons like Brexit and the German AfD party, which in turn pose a danger to the prosperity and peace we enjoy in Europe.
