Section 3.5 says:

Original Text
-------------
t= Signature Timestamp (plain-text unsigned decimal integer;
      RECOMMENDED, default is an unknown creation time).  The time that
      this signature was created.  The format is the number of seconds
      since 00:00:00 on January 1, 1970 in the UTC time zone.  The value
      is expressed as an unsigned integer in decimal ASCII.  This value
      is not constrained to fit into a 31- or 32-bit integer.
      Implementations SHOULD be prepared to handle values up to at least
      10^12 (until approximately AD 200,000; this fits into 40 bits).

Corrected Text
--------------
Ditto, but 10^12 a.k.a. 40 bits is not AD 200,000.
(Unless this goes in line with Paul McCartney's "three thousand or fouurr 
thouuuusand" in the Cavern Club appearance in 1999, the first after his wife 
died.)

It rather is

$ xa '  10**12  / 60 / 60 / 24 / 365'
0b 00000000 00000000 00000000 00000000 00000000 00000000 01111011 11011101
075735 | 0x7BDD | 31709

(with 40 bits really being
$ xa '  ((2**40) - 1)  / 60 / 60 / 24 / 365'
0b 00000000 00000000 00000000 00000000 00000000 00000000 10001000 00110001
0104061 | 0x8831 | 34865)

So "approximately AD 32000".

Notes
-----
Maybe an iterated DKIMv1 needs this clarification.
