As I understand it, the premise of the method is that, at day D, you already have written the contents of tweet Tr (to be posted as a reply to T) and so you can already compute its hash and tweet the hash as part of T on day D. Then on day D+N, you tweet Tr, which hashes correctly to what you said it would, and thus is extremely unlikely to have been tampered with.
Where does the date string contained in Tr come into play?

Google introduced exactly this to one of their internal services so that downstream dependencies can't rely on its extremely high availability.
They are in enterprise, but I digress
And this is why I shop at Uniqlo, not at H&M or Zara. I like to ensure that my favourite basics will always be available for repurchase 2+ years after the original purchase, so I can replace a worn item.
If that's true, how is it reasonable to allow this equipment to operate in the UK for 7 more years? Doesn't that mean the UK is willingly under national security risk for 7 years?
Unless, of course, there was never a security risk...
They can't do that remotely?
