That's TAI64, an epoch count based on the time scale TAI. TAI 64 starts at Jan 1, 1970 (TAI) = Dec 31, 1969 23:59:xx UTC.
You mean _TAI32_ starts at Jan 1, 1970 (TAI), right? I'm not able to find _any_ definition/implementation of TAI32 on the web, nor am I able to find anything useful about TAI at all, except on Dan Bernstein's pages. The website http://www.bipm.org is singularly useless, even when compared to other international standards bodies.
<wild speculation>
I'm sure there is much more useful information listed in the French version of http://www.bipm.org.
