It did not happen. A quick check on SDR.hu on the Fort Collins CO SDR this morning and WWV is ticking right along on 2.5, 5, 10, 15, 20, and 25 MHz.
WWV/WWVH/WWVB is run by the National Institute of Standards and Technology (NIST) which is under the Department of Commerce (DoC). Since DoC is part of the ongoing partial government shutdown, I cannot say that the shutdown won't still happen. But for now, that tick-tock continues from the Colorado/Hawaii Standard Frequency and Times Stations (SFTS).
