Annotation Interface CreationTimestamp

@Retention(RUNTIME) @Target({FIELD,METHOD}) public @interface CreationTimestamp
Specifies that the annotated field of property is a generated creation timestamp. The timestamp is generated just once, when an entity instance is inserted in the database.

By default, the timestamp is generated by in memory, but this may be changed by explicitly specifying the source(). Otherwise, this annotation is a synonym for @CurrentTimestamp(timing=INSERT,source=VM).

The annotated property may be of any one of the following types: Date, Calendar, Date, Time, Timestamp, Instant, LocalDate, LocalDateTime, LocalTime, MonthDay, OffsetDateTime, OffsetTime, Year, YearMonth, or ZonedDateTime.

A field annotated @CreationTimestamp may not be directly set by the application program.
