The following are some known issues and limitations for MySQL Connector/J:
When Connector/J retrieves timestamps for a daylight saving time (DST) switch day using the
getTimeStamp()method on the result set, some of the returned values might be wrong. The errors can be avoided by using the following connection options when connecting to a database:
The functionality of the property

MySQL Server uses a proleptic Gregorian calendar internally. However, Connector/J uses
java.sql.Date, which is non-proleptic. Therefore, when setting and retrieving dates that were before the Julian-Gregorian cutover (October 15, 1582) using the
PreparedStatementmethods, always supply explicitly a proleptic Gregorian calendar to the
getDate()methods, in order to avoid possible errors with dates stored to and calculated by the server.
