# offsetsForTimes

`abstract fun offsetsForTimes(topicPartitionTimestamps: MutableMap<TopicPartition, Long>, handler: Handler<AsyncResult<MutableMap<TopicPartition, OffsetAndTimestamp>>>): Unit`

Look up the offsets for the given partitions by timestamp. Note: the result might be empty in case for the given timestamp no offset can be found -- e.g., when the timestamp refers to the future

### Parameters

`topicPartitionTimestamps` - A map with pairs of (TopicPartition, Timestamp).

`handler` - handler called on operation completed

`abstract fun offsetsForTimes(topicPartition: TopicPartition, timestamp: Long, handler: Handler<AsyncResult<OffsetAndTimestamp>>): Unit`

Look up the offset for the given partition by timestamp. Note: the result might be null in case for the given timestamp no offset can be found -- e.g., when the timestamp refers to the future

### Parameters

`topicPartition` - TopicPartition to query.

`timestamp` - Timestamp to be used in the query.

`handler` - handler called on operation completed
