Yes, we will do so soon after 1.8.1 anyway, for the foodbox,
unit upkeep, governments, etc.

Though actually, the [calendar] doesn't really introduce any
client-server incompatability does it?  Because it doesn't send
anything to the client, and I think the client just uses whatever 
year the server tells it it is.  

(Though a client-side AI might want to know more?  Probably only
for spaceships though.) 

And server-side, its easy enough (and IMO, almost mandatory) 
to make the server backward compatible with old savefiles etc.

Because spaceship travel times are in years, not turns, and it
was considered a good idea to have 1 turn per year by the time
spaceships are possible.  That way, when someone launches
a spaceship, you are guaranteed a number of turns to react,
rather than possibly the spaceship arriving the next turn.
