org.apache.hadoop.hive.serde2.io.TimestampWritable
TimestampWritable Writable equivalent of java.sq.Timestamp Timestamps are of the format YYYY-MM-DD HH:MM:SS.[fff...] We encode Unix timestamp in seconds in 4 bytes, using the MSB to signify whether the timestamp has a fractional portion. The fractional portion is reversed, and encoded as a VInt so timestamps with less precision use fewer bytes. 0.1 -> 1 0.01 -> 10 0.001 -> 100
