A quick googling lead to https://github.com/jasonabele/gr-wwvb I don't know anything about it so use at own risk :) But at least it seems like something that can be done easily on a rainy evening. Normal RTL-SDR's do not work for WWVB as they have a lower cut of frequency in the range of 20-50MHz...unless you bypass the tuner chip and feed the signal directly to the ADC. As IIRC all RTL-SDR give you something like 2Msps, that should be more than plenty to decode WWVB and related signals. If you feed the RTL-SDR from an external frequency source, you should be able to related that frequency source to WWV.
