because if the bios battery is losing out then you will start getting problems with bios config changed and u would need to go back into it and have hard drives etc re-detected on some boards. anyway, if the bios is correct in its time, then windows is not updating either due to win errors, or a 3rd party program changing time via internet connections, etc. it just all depends on checking the bios time.
If you argue with an idiot he will drag you down to his level and beat you with experience.
