I implemented custom UtcTimestampType in hibernate to always save time in UTC.like discussed http://stackoverflow.com/questions/5080 ... 3#16955113 . In this post it was suggested that all the over ridden methods are delegated to TimeStampType. I am not sure of role these methods play, is it ok to delegate to TimeStampType? What is the importance of over-riding below methods ?: i am using hibernate 5.0.1.

1 . String[] getRegistrationKeys() in org.hibernate.type.BaseType
2. seed, next, getComparator in org.hibernate.type.VersionType<T>
3. objectToSQLString in org.hibernate.type.LiteralType
