Comparing a $2.00 chipset WWVB receiver, when the chipset by design uses an antenna of a few square inches and will only even try to sync in the middle of the night, with anything else is completely out of whack. I could just as well pull out a crappy $15 GPS receiver from the surplus market ten years ago - The Trimble SV6 - and show you how the timing pulses from it jitter up and down by 6ms depending on whether 3 or 4 satellites are in view.
