TemporalBinningStrategy assumes milliseconds.
Many of the temporal data processed by GeoWave is second granularity.
Configuring the strategy with second instead of millisecond reduces the scale of each hypercube.

TimeDefinition takes a unit defines unit for bin size.
TimeDefinition should a unit defines unit for bin size AND time unit size.

Note: Time/Date is still presented as a java.util.Date, which is millisecond granularity.
Is their a general solution to choose the granularity?
