public class TimeDataGeom extends Object implements DataGeom
Note the first coordinate is time, whose values are in seconds since
the Unix epoch, as defined by TimeMapper
.
This is a singleton class.

DataGeom
A parameter supplies the index of the field in the tuple
at which the positional coordinate(s) can be found.
Each position is represented by DataGeom.getPosCoords()
columns of
the tuple.
By convention positions are at the start of the tuple,
so if there is one position in the tuple it will be at icol=0,
and there are multiple positions the N'th one will be at
icol=N*getPosCoords().
An array of (at least) DataGeom.getDataDimCount()
elements is
supplied, and on success the data space coordinate values
are written into it.
