从接口复制的说明: IReaderByTimestamp

Returns the corresponding value under this timestamp. Returns null if no value under this timestamp.

Note that calling this method will change the status of this reader irreversibly just like next. The difference is that next moves one step forward while getValueInTimestamp advances towards the given timestamp.

Attention: DO call this method with monotonically increasing timestamps. There is no guarantee of correctness with any other way of calling. For example, DO NOT call this method twice with the same timestamp.
