t,,,,,, This term returns true if two timeframes (defined by their endpoints) are overlapping, true if they are not. End points can be specified as a couple of date, time, or timestamps; or as a date, time, or timestamp followed by an intervall. If a value couple is provided, either the beginning or the end can be spelled first; OVERLAPS uses the previous value of the couple as the starting point by default.

Every time span is regarded as the half-open beginning of the intervall
