Every day, Windows 10 keeps falling behind a few seconds every day. It starts of at like 0.5 seconds and as the week goes own, falls as far behind as 7 seconds. I have scanned with Malwarebytes and Windows Defender multiple times and nothing was found, my pc is set to sync with time.nist.gov and to set the time zone automatically. My computer is just 1 years old which makes me think it's not my CMOS battery as it usually takes far longer for them to die
For reference, I use time.is to see how accurate my time is...

Based on what you have stated above, I would change the CMOS battery. They are inexpensive. Usually a CR2032
Someone suggested not turning it off at the power source fixed their issue, I'll see if that fixes it. Keep an eye on the thread and I'll update you as to if it worked

2018-08-25T20:49:05+00:00 The primary clock and its ability to keep time is a function of the computers hardware not the operating system. However, the operating system does provide for synchronizing the on board hardware clock to an external time source. This syncing occurs periodically.
If it is becoming inaccurate between synchronizations, I would suspect hardware.
The battery keeps the clock running when the power is off, so if the time is changing when the computer is in use, it is not the battery.
