The best-fit Java class for an Informix DATETIME value is java.sql.Timestamp. Java.sql.Timestamp technically inherits from java.util.Date; although, there are some semantic differences which are not typical of inheritance relationships. All the constructors, getters, and setters which are not deprecated for Date and Timestamp use values based on Greenwich Mean Time (GMT). They are offsets in milliseconds from the epoch, January 1, 1970 00:00:00 GMT. So, it would be logically consistent for Timestamps to convert to DATETIMEs using the GMT... [More]
