Relative Dates

Many adventures and published campaigns have some fuzzy dating in which the GM must manage the eventual date/time of something "A week ago," "last month," "in a few days," and "x years ago" are pretty common examples in published adventures and campaigns. However, RealmWorks does not support such vague time references; it uses specific dates and times. It would be nice if there was some way to make dates relative to another date/time element .. even if that has to be a list of a fixed number of such "anchor dates" for a single Realm.
