Examples of ch.agent.t2.time.DateTime

ch.agent.t2.time.TimeIndex
A DateTime is a {@link Time2} with second resolution and the origin at2000-01-01. For times before the origin, {@link TimeIndex#asOffset()} will returnnegative values. The domain label is datetime.
This time corresponds to Unix time, except for the "epoch", 2000-01-01 instead of 1970-01-01. @author Jean-Paul Vetterli
