BIOS - Real Time Clock RTC reverted back or paused -NOT A CMOS Battery Problem!

TRIED ALL YOUR MINI PC's

you're probably have problem in the Real Time Clock (RTC) AND IT'S NOT CMOS BATTERY PROBLEM

the real time clock just resets back to default time and date (December/2016 00:00)

i have more than 30 pcs of Intel NUC5CPYH updated to Bios version 0064 All of them are new.

bought at different dates

The reason is that i'm the only one who complains about that problem is because of i'm using this nucs in offline-mode and it's impossible to connect them to the internet for time synchronization always

i checked voltage of cmos battery - it's correct (3v) and you all agree with me that it can't be that more than 30 pcs has the same problem

1. THE TIME AND DATE ARE STOPPING FROM MOVING

2. SOME OF THEM ARE REVERTING BACK DECEMBER 2016 00:00

3. IN SOME OF THEM THE TIME AND DATE STOOPING/REVERTED TO DEFAULT WHEN THEY ARE PLUGGED OUT OF POWER FOR 3-4 DAYS OR SO...

I have big organization of my customers that i sold the nuc for them, and now they want to fill a lawsuit against me because of that! it's absolutely not a operating system related issue because i see the time and date stop / revert problem as soon as i hit F2 to the bios , before the operating system boots up and i tried also to remove the hdd and see if it happens to nucs that stays offline without hdd - it happens!

tried every scenario you could imagine , including replacing the cmos battery although it's new nucs units (3 weeks-2 months since opening the box maximum)

IT'S ABSOLUTELY a BIOS BUG that you never could test at your development because i guess you and most of your customers using them with an internet connected and time sync ability.

please solve this issue for me , i'm bagging you i'm here any time to do any test that you want online with you 24 else i will get into big trouble with my customers and lose big money.

NO CMOS ERROR / CMOS LOW BATTERY OR ANY ERROR MESSAGE IS LOGGED OR SHOWN DURING BOOT

Just for your notation According to this page https://www.intel.com/content/www/us/en/support/articles/000006787/mini-pcs.html CMOS Battery on the Intel® NUC

You tell customers that the CMOS battery do responsible for keeping the time running during power off for 3 years.

I'm sure this bug is not battery related issue after what i've tried

to test you must use a unit without any connection to the internet for time and date syncing

This is an issue that is beyond the normal Q&A done here on the Communities site. You should have it directly handled by Intel Customer Support. Contacting them by phone is my recommendation.

I am also having this same problem - I have about 20 Intel NUCs, all about 2-3 years old, and for compliance/security purposes none of them are connected to the Internet. When I start them up Windows displays the wrong time. I've discovered it's because the BIOS time is incorrect (November 2017 or January 2016 for example). I boot into BIOS and set the correct time. Save and exit. Later on, the BIOS time reverts back. Extremely annoying. Has anyone found a solution to this?

Which NUC model(s) are you using? NUC5CPYH like the first user?
