Hi Richard, Interesting! A few immediate comments / questions:
1) Political talk to /dev/null 2) Whether as executive order or otherwise, language like this obviously originated with experts. 3) Does anybody know what agenc(ies) appears to be motivating this? 4) Are commercial interests involved? 5) Are similar actions being taken in Canada or other countries? 6) Is PNT singled out, or are there similar orders for other technologies and risk profiles? 7) I don't see "leap second" or terms like "NTP" mentioned here. Six months is remarkably aggressive, even notionally, and there's no definition of what "source of UTC" means, or even "GNSS-independent". Is some specific technology or even vendor already implied?
