I've postgres data source in grafana and I've a table with "time without timezone" type column.
The problem is when I try to use it in grafana it interprets column as timestamp with date. So the result is like "1753-08-30 07:13:58.129" instead of "06:00".
Is there a way to show time only columns in grafana?

I am using pgAdmin to browse a database hosted at Heroku. I am trying to create new records but I am getting an error because there is a column of type timestamp with time zone. I want the time zone to be UTC+3. Here is what I have tried, but I am getting an error:
Here is the value if you need to copy/paste it:
1477357140.0+03
Is there any method to create the records without converting the timestamp value from the unix-time format?
Is it a requirement that you must use a time or datetime column in postgres to pull metric's on a Grafana dashboard?
I ask because I have a column just with a date only and I'm unable to show metrics base on dates only. Unless I am missing something in the documentation. Postgres in Grafana
If anyone has any helpful information, it would be greatly appreciated.
All I need is just a starting point.
I am a new user to Grafana and I'm trying to figure this out.
According to documentation:
If you set Format as to Time series, for use in Graph panel for example, then the query must return a column named time that returns either a sql datetime or any numeric datatype representing unix epoch in seconds.
So, all you need is to convert your column with date to unix epoch and name it as time. You can do it yourself or use macros provided by grafana (see docs) for convertion which are expanded into native postgres expressions. It is also helpful to look at 'Generated SQL' to see the actual query sent to database.
We are moving BackEnd tables from a large MS Access application to postgresql.
In one table we have a field ErZei defined in postgres as
time(0) without time zone DEFAULT ('now'::text)::time(0) without time zone
Inside this field only the time value is stored, the day value has his own field.
The linked table inside Access shows the current day in front of the time value. Using the 24-hour format for displaying time values in Access looks fine. But by entering the field, the current day appears automatically.
If I call the time field by SQL-Query SELECT * from ..., I get the same result: everytime the current day value in front of the time value.
Inside postgres everything works fine.
Also a test with a ODBC query tool shows only the time.
How could I configure MS Access to show only the time value without the day in case of postgres time columns?
I can't find an option in the Access globals.
We use
MS Access 2016
ODBC: PostgreSQL Unicode 10.00.00 PSQLODBC35W.DLL
13.10.2017
PostgreSQL 10.1 as backend on ubuntu
Redshift only support TIMESTAMP format, I want to dump some data that is originally stored in Postgres in time without time zone format. My data looks like this: 15:30:00
When I COPY my data into Redshift, it says Invalid timestamp format or value [YYYY-MM-DD HH24:MI:SS], error code 1206.
My current workaround is to create that column in Redshift as CHAR(8)
Thanks
There's no other solution that to use the char(8).
Redshift does not support timezones.
Workaround would be to parse data to UTC and store time difference in separate column. You will be able to calculate local time by adding/substracting hours to the UTC data.
I am reading a csv file with date fields of formatted mm/dd/yyyy. I expected the same kind of format from a Postgres table after the import, but I see yyyy-mm-dd hh:mm:ss.
The date fields in my table are defined as timestamp without time zone data type.
How do I maintain the same format of data? I am using PostgreSQL 9.3.
Postgresql only stores the value, it doesn't store formatting (which would waste space).
You can use the to_char function in your query if you like to get the output formatted in a special way. Details are in the manual.
