When I am updating an record, there is one field that belongs to the class (birth date). This field it is a date Object (or datetime data type if I were using C#). When I save such record in the database, the record is updated with success, but, when I look for this record on the database(MySQL), this field is showing a wrong date value. Month and Year values are correct, but day value is showing a day before that I typed.

Is there some parameter that I need to configure to work with java.util.date class ? In my database table, I defined this field with the same type as I am using in my class. I am using eclipse to work with JSF and working with Java sdk 1.6.18.

When I put breakpoints in my code for debug, I noticed that the Date object is using Gregorian Calendar, but unfortunately it already comes with a wrong date value. I checked my datetime settings, and they are setup correctly. I am using UTC -03:00 (Brazil)

    Code? ORM-mappings? Also, java.util.Date kinda sucks, you should use Joda-time's DateTime instead.. – Tobb Sep 24 '12 at 20:23

    The issue with `java.util.Date` being internally UTC never gets old http://stackoverflow.com/questions/12571769/h2db-and-java-an-approximate-two-hour-discrepancy/12571885#12571885 – SJuan76 Sep 24 '12 at 20:29
  • Hi Tobb, I guess I did left some piece of information missing, isn't it? Well, as I told before, I'm working with Hibernate as ORM Tool. I followed all book steps and I guess the class it is mapped correctly, but I really don't know what I might be doing wrong. I saw you mentioned about Joda-time's DateTime. What would be this Joda-time's DateTime? I would like to remark that I am a newbie about programming in Java, especially for web. – TuLePe Sep 24 '12 at 20:45
  • Joda-time is a time and date framework that does the job right. The java.util.Date is decent for simple usages, but lacks in many respects, when it comes to increasing and comparing dates for instance. When it comes to your proble, you might want to check the default locale of your system. You can do that by calling Locale.getDefault(). It might be set to a different timezone than you expect.. – Tobb Sep 24 '12 at 21:58
