Ajustarea incorecta/imperfecta a ceasului dispozitivului cu windows la logare

Daca avem un dispozitiv cu sistemul de operare windows (x64) si observam o desincronizare (ramanere in urma a datei/orei (ori opusul)), observam ca uneori se efectueaza sincronizari la logarea cu un user de domeniu. Totusi, aceasta sincronizare este imperfecta si are mari variatii.

Deoarece nu dorim disfunctionalitati in procesul de utilizare a aplicatiilor web (si nu numai), este important sa avem ceasul sincronizat cu o precizie sub cateva sute de milisecunde.
