SUMMARY If I manually change the system clock, it will ask for the administrator password two times in a row. STEPS TO REPRODUCE 1. Right-click the system clock, select "Adjust Date and Time", untick "Set date and time automatically". 2. Optionally, apply the settings, exit the menu, and get into the same menu again. 3. Manually change the system time. OBSERVED RESULT Will ask for administrator password twice. EXPECTED RESULT Should ask for administrator password only once.

Can confirm.
Plasma does not control this behavior. It only makes DBus calls to timedated, the authorization part is purely internal to timedated/polkit.
