    dbtimezone

    Hi,

    Our client in Fiji is going for DST change starting from this year. When I am querying the views (created using cre_tz_views.sql) i found dbtimezome is different in some databases. In some databases it is +12, in some +5, and in some -7.

    The query I used is 'select dbtimezone from dual;'

    None of the applications are using names timezone data types.

    Appreciate your input to know how the difference in dbtimezone makes difference.

    Thanks,
    Vijay Tummala

    The database takes the time from its server. So whatever timezone the server is set to the database will show that timezone.

    Hope this answers your question.

    yes, I agree that database takes time from server. But I don't agree the same for timezones. In the below example from one of my servers, OS time zone seems to be GMT+12 and dbtimezone is +00:00 but still is showing the date /time correctly.

    So, I am trying to understand the user of dbtimezone.
