An action stamp is a format I invented in reposurgeon for pointing at
commits in a repository in a way independent of topology or SHA-1 hashes;
this is sometimes required when doing repository surgery.  It looks like this:

<2017-01-23T15:57:15Z!esr at thyrsus.com>

which means "the commit (or, in rare cases, commits) made by esr at thyrsus.com
at 2017-01-23 15:57:15 UTC".

NTPsec makes no use of it.
