             Summary: Times Inserted Incorrectly Around Daylight Savings Time Change in Spring
                 Key: DERBY-7091
                 URL: https://issues.apache.org/jira/browse/DERBY-7091
             Project: Derby
          Issue Type: Bug
    Affects Versions: 10.14.2.0
         Environment: Java 14.0.1
            Reporter: Larry Melvin Lemons
         Attachments: Timezone_Data_Inconsistencies.odt

When inserting date/times into the timestamp field around the daylight savings time change in the Spring, the times are inconsistent.  I am in/use the New York EST/EDT timezone, but the data I am inserting is Standard time and not Daylight Savings Time

All the times are correct up to 1:48AM, then when it inserts 2:00 AM the data in the database is 3:00AM.  That could be alright if it kept switching the time to Daylight Savings Time, however going from inserting 2:48AM and getting 3:48AM in the database, when it inserts 3:00AM it shows 3:00AM in the database, not the expected 4:00AM.  Then in the fall whatever is inserted in the database is what shows in the database around the daylight savings time switch to standard time.  See the attached Open Document Text file for examples of what is actually inserted and what is showing in the database.
