You're right, of course. Nevertheless, it's still a win over time_t. 
Let's assume time_t uses a long int under the bonnet, and let's further 
assume that it encodes seconds (a not uncommon implementation, as we 
both know). On a 32-bit-long-int system, that gives us a range of 49710 
days, which is 136+ years. Julian dates, on the same system, can cover 
well over 11,000,000 years.

I have no particular need for /millions/ of years, at least not yet, but 
I find the ability to stretch back through the second millennium (and 
even into the first) to be useful from time to time.
