I don't think you need to override this in 0.10, right?
The implementation is basically identical to the base implementation.
> FlinkKafkaConsumer should support to use timestamp to set up start offset

> Key: FLINK-6352
> URL: https://issues.apache.org/jira/browse/FLINK-6352
> Project: Flink
> Issue Type: Improvement
> Components: Kafka Connector
> Reporter: Fang Yong
> Assignee: Fang Yong
> Fix For: 1.4.0
>
>
> Currently "auto.offset.reset" is used to initialize the start offset of
> FlinkKafkaConsumer, and the value should be earliest/latest/none. This method
> can only let the job comsume the beginning or the most recent data, but can
> not specify the specific offset of Kafka began to consume.
> So, there should be a configuration item (such as
> "flink.source.start.time" and the format is "yyyy-MM-dd HH:mm:ss") that
> allows user to configure the initial offset of Kafka. The action of
> "flink.source.start.time" is as follows:
> 1) job start from checkpoint / savepoint
> a> offset of partition can be restored from checkpoint/savepoint,
> "flink.source.start.time" will be ignored.
> b> there's no checkpoint/savepoint for the partition (For example, this
> partition is newly increased), the "flink.kafka.start.time" will be used to
> initialize the offset of the partition
> 2) job has no checkpoint / savepoint, the "flink.source.start.time" is used
> to initialize the offset of the kafka
> a> the "flink.source.start.time" is valid, use it to set the offset of kafka
> b> the "flink.source.start.time" is out-of-range, the same as it does
> currently with no initial offset, get kafka's current offset and start reading
