public class TimeMatrix extends AbstractDoubleMatrixAbs<TimeUnit,DurationUnit,TimeMatrix,DurationMatrix,MutableTimeMatrix,Time>
Note that when the offset of a stored absolute Time becomes large, precision of a double might not be enough for the required resolution of a Time. A double has around 16 significant digits (52 bit mantissa). This means that when we need to have a double Time with TimeUnit.BASE as its unit, the largest value where the ms precision is reached is 2^51 = 2.3E15, which is around 71000 years. This is sufficient to store a date in the 21st Century with a BASE or an Epoch offset precise to a microsecond.
