Carl,

Another thing the ASCII representation complicates is adding a
relative time to an absolute time... i.e., to compute an expiration
time from an issuing time.

This is commonly done by certificate issuers.  Since SPKI views this
as a relatively light-weight process, I think it's worth considering
this as well.  There's also the factor of compactness; kerberos went
from 4-byte to ~16+-byte asn.1 ascii timestamps from v4 to v5, which
contributed significantly to the bloat in the size of tickets from v4
to v5.
