You already have various unixTimeToXXX functions, so it's probably moot, 
but with an epoch, such operations are dead simple:

auto t = UnixEpoch + time().seconds;

I see very little value in a wrapper function to do this. But it's 
already there, so...

BTW, I think with UFCS, having the 'seconds' etc. functions is one of 
the coolest parts of D's time library. I love that part :)
