/**
 * Easy access methods for the FloatTime FloatScalar.
 * <p>
 * Note that when the offset of a stored absolute FloatTime becomes large, precision of a float might not be enough for the
 * required resolution of a Time. A float has around 7 significant digits (23 bit mantissa). This means that when we need to
 * have a float time that is precise to microseconds, the FloatTime value should not go above 2^22 = 4.0E6. This is <b>not</b>
 * enough to store Epoch values that are in the order of magnitude of 2E12 ms! So feeding System.TimeInMillis() to a FloatTime
 * with TimeUnit.BASE as its unit is not having the required precision. At best, a FloatTime can store TimeUnit.BASE or
 * TimeUnit.EPOCH values with real calendar values with a precision of several minutes.
