pub const MAX_LIFETIME: i64 = 315_576_000;Expand description
The furthest past now, in seconds, that a token’s exp may lie: ten
years of 365.25 days, as macula_ucan:max_lifetime/0. UCAN_V1 has no
revocation, so exp is the only bound on a token’s life. An exp in
milliseconds lies far beyond it, so a token minted with one is refused,
by create and by authorize, rather than valid for tens of
thousands of years.
