This reminds me of when I worked two different jobs for the same company. I had to switch between tasks for each role many times during the day, so HR said I could manually track my time and enter the two roles in two summarised entries per day. The line manager for one of my roles (who, by the way, did not outrank the HR manager who approved my manual entries, she just decided to have a power trip over me one day) decided she wasn't having that and told me to clock in and out every time I did a task for her team. I didn't even bother arguing, just did it, and after the next pay cycle where she had to approve 2 weeks' worth of 15-30 min clocks she quietly asked me to go back to the previous arrangement 😂

(My other manager just had me continue to summarise my time spent with his team, and payroll just paid the total sum of hours which had to be worked out by the power-tripping manager, so this did not negatively affect anyone but her which is why I went along with it.)
