+/**
+ * Immutable SQL TIMESTAMP type with nanosecond precision.
+ *
+ * <p>This class is composite of a millisecond and nanoOfMillisecond. The 
millisecond part
+ * holds the integral second and the milli-of-second. The nanoOfMillisecond 
holds the
+ * nano-of-millisecond, which should between 0 - 999_999.
 
 Review comment:
   No. They have the same range. The differences is:
   `java.sql.Timestamp` holds integral second plus nanosecond(with milli-part), 
and
   `DateTime` holds integral second(with milli-part) plus nanoOfMillisecond.
