Hi Ian,

what exactly are you meaning with 'make the column a timestamp'? Because in 
GeoServer I already tried to change the data type to 'Timestamp' and that 
doesn't change anything. And in the Oracle database the DATE type also stores 
time values. From the documentation: "The fields that apply to all Oracle 
Database datetime and interval data types are: YEAR MONTH DAY HOUR MINUTE 
SECOND." 
(https://docs.oracle.com/en/database/oracle/oracle-database/23/nlspg/datetime-data-types-and-time-zone-support.html#GUID-789689BF-5682-4577-8ADE-8105C652CBB7)

So would it be necessary to change the data type inside the database? And why 
are values on the afternoon or evening set to noon instead of midnight if only 
year, month and day are preserved?

Thank you
Daniel

columns

That's the expected behaviour - if you need to preserve the time of the date 
make the column a timestamp (preferably with timezone) rather than a data which 
only stores the year, month and day.

Hi,

I just discovered that GeoServer is rounding Oracle DATE attribute values down 
to zero or twelve hours when I'm publishing data from a 'Oracle NG (OCI)' data 
store. Examples:

1.1.2024 17:34:12 becomes 1.1.2024 12:00:00 or
1.1.2024 03:17:05 becomes 1.1.2024 00:00:00

This happens only when I'm publishing a complete table, not when I'm defining 
an SQL view. Directly after creating the new layer, the column type is set to 
the Java data type 'Date'. Comparing to an SQL view I saw that there the column 
is defined as 'Timestamp'. But also changing the data type using the 'Customize 
attributes' function to 'Timestamp' or 'Time' doesn't help.

This happend in GeoServer 2.23.0 and also 2.25.0.

Does anybody have an idea what's going on here.

Thank you and best regards
Daniel
