Class DateTimeCodec

java.lang.Object

com.datastax.driver.core.TypeCodec<T>

com.datastax.driver.core.TypeCodec.AbstractTupleCodec<DateTime>

com.datastax.driver.extras.codecs.joda.DateTimeCodec

public class DateTimeCodec
extends com.datastax.driver.core.TypeCodec.AbstractTupleCodec<DateTime>

TypeCodec that maps DateTime to CQL tuple<timestamp,varchar>, providing a pattern for maintaining timezone information in Cassandra.

Since Cassandra's timestamp type preserves only milliseconds since epoch, any timezone information would normally be lost. By using a tuple<timestamp,varchar> a timezone ID can be persisted in the varchar field such that when the value is deserialized the timezone is preserved.

IMPORTANT: this codec's format method formats timestamps using an ISO-8601 format that includes nanoseconds. This format is incompatible with Cassandra versions < 2.0.9.
