That is correct. It's been 1007 Darduni years since the Twilight Wars. Some nations, however, restart their calendars when a new isvar or aminar takes the throne (and they'd say it was the 23rd Year of the Reign of Kelentos IV, for example), so that creates all kinds of problems. And Sustrum counts their year from the founding of their amin (those damn cats). But in general, it is accepted that the year is 1007 since most of the world's calendars began again after the Twilight Wars.

And the published modules do in fact take place around that year (some may play with that, though).
