Ken Thompson is at google these days - might be interesting to ask if there was a point between v6 and v7 where it was used as 'creation time'. https://www.tuhs.org/Archive/Documentation/Papers/BSTJ/bstj57-6-1905.pdf looks like a reference to 'creation time' in Apr 78, and man/man5/filsys.5 is Jan 79 (already matching actual behaviour of released v7). I wonder if anything of Interdata 8/32 port survives...
