While I apologize for making general claims without a significantly larger sample size, I have tried this on all of my devices and those of family and friends.

While I apologize for making general claims without a significantly larger sample size, I have tried this on all of my devices and those of family and friends. I only have access to phones running Android and laptops/desktops running Windows, so I cannot say whether macOS/iOS and Linux suffer from the same issue. I'm looking at ~12 devices from various manufacturers that all have similar amounts of clock drift. All of the devices have network sync enabled, and they sync to accurate time if I manually disable and enable it again. The issue is that they don't sync regularly enough by themselves.
