/**
 * A mapping from SQL's Timestamp to Java's LocalDateTime.
 * 
 * The mapping is naive, and will not include or consider timezone or the similar.
 * Instead, the mapping will be direct: what is written in the database will
 * be directly mapped into Java.
 * 
 * Example: 

 * In database: '2016-08-01 09:39:45'

 * In Java: 2016-08-01T09:39:45
