类 TimestampType

java.lang.Object

com.pingcap.tikv.types.DataType

com.pingcap.tikv.types.AbstractDateTimeType

com.pingcap.tikv.types.TimestampType

所有已实现的接口:

Serializable

public class TimestampType
extends AbstractDateTimeType

Timestamp in TiDB is represented as packed long including year/month and etc. When stored, it is converted into UTC and when read it should be interpreted as UTC and convert to local When encoded as coprocessor request 1. all date time in key should be converted to UTC 2. all date time in proto should be converted into local timezone 3. all incoming data should be regarded as local timezone if no timezone indicated

For example, Encoding: If incoming literal is a string '2000-01-01 00:00:00' which has no timezone, it interpreted as text in local timezone and encoded with UTC; If incoming literal is a epoch millisecond, it interpreted as UTC epoch and encode with UTC if index / key or local timezone if proto
