+ * Specifies the consumer to start reading partitions from specific
date. The specified date must before curr timestamp.
+ * This lets the consumer ignore any committed group offsets in
Zookeeper / Kafka brokers.

+ * The consumer will look up the earliest offset whose timestamp is
greater than or equal to the specific date from the kafka.
+ * If there's no such message, the consumer will use the latest offset
to read data from kafka.
