Section 6 says:

| 1 Jan 1972  | 41,317     | 0   | 2,272,060,800 | First day UTC    |

It should say:

| 1 Jan 1972  | 41,317     | 0   | 2,272,060,800 | First day "modern" UTC |

Notes:

The initial definition of UTC was introduced in 1963 with CCIR Recommendation 374. The time standard specified that seconds had a varying duration. In 1970, CCIR Recommendation 460 introduced the current definition of UTC, using leap seconds, which was implemented on the first second of 1972. Consult D. McCarthy's "Note on Coordinated Universal Time" (numbered CCTF/09-32 by the Consultative Committee for Time and Frequency of the BIPM) for more information.
