[LEAPSECS] RIP dmr, -893400000 to 1318100000

[Zefram]

It's being reported that Dennis Ritchie, the inventor of Unix time
among other things, died about 500 ks ago.  His life spanned -893400000
to 1318100000 in Unix time.  And now we can no longer ask him for
clarification about whether the count was meant to include leap seconds.
