Information in this document applies to any platform.
When inserting timestamps into the database, the timestamp information may be incorrect during occasions when there is a time change, such as Daylight Savings Time (DST). The problem occurs during the hour that is repeated after moving the clock back (for example, between 1 AM and 2 AM).
For example, given an 22.214.171.124 JDBC driver and an 126.96.36.199 database:
In the database, the value for a timestamp column is 1924-03-30 00:00:00.
When writing the same value through JDBC, it is written as 1924-03-29 23:00:00.
In other words, the values differ by an hour.
