I must say the current time system is very confusing, especially when it comes to what year it is. But I understand that the difference in time scale will always make things difficult, though.
However, couldn't it somewhere say what date it is? Like where it says 'Spring', change it to 'Spring, in the 5th year of Dwilight'?
(If that's to plain, you could even have realms decide when their calendar starts, as in 'Spring, in the 12th year after the Fall of the Kepler Stronghold'. But that's more than I'm asking for)
