Event triggers created_at time shifted +09:00

[tatsuhirokasai]

Version Information

Server Version: v2.40.0

Environment

OSS

What is the current behaviour?

The created_at values displayed on the Processed Events page and Invocation Logs page in the Hasura Console are offset by 9 hours.

What is the expected behaviour?

The values should display the actual time when the events were executed (i.e., the values should reflect the time 9 hours earlier).

How to reproduce the issue?

1. Create an event that triggers when data is INSERTed into any table.
2. Perform an INSERT operation on the table.
3. Check the logs on the Hasura Console's Events page.

Any possible solutions/workarounds you're aware of?

Execute the following SQL commands:

ALTER TABLE hdb_catalog.event_invocation_logs 
ALTER COLUMN created_at TYPE TIMESTAMPTZ;

ALTER TABLE hdb_catalog.event_log
ALTER COLUMN created_at TYPE TIMESTAMPTZ;

Hey @tatsuhirokasai, thanks for raising this issue.
I'm not able to reproduce this issue on my machine. Can you tell me more about the issue you are facing -

1. Was the local time when the event was triggered shown correctly on the console i.e. 11:22 PM? If yes, then the +9:00 actually represents that your local time is 9 hours ahead of UTC.
2. Also give me the time zone of your Graphiql Engine, Postgres server and Browser.
3. Is your Postgres server migrated from some other timezone?

ALTER TABLE hdb_catalog.event_invocation_logs
ALTER COLUMN created_at TYPE TIMESTAMPTZ;

ALTER TABLE hdb_catalog.event_log
ALTER COLUMN created_at TYPE TIMESTAMPTZ;

Hey @Varun-Choudhary , Thank you for checking. Here are the answers to your questions:

1. Was the local time when the event was triggered shown correctly on the console i.e. 11:22 PM? If yes, then the +9:00 actually represents that your local time is 9 hours ahead of UTC.

The actual event occurred at 2:22:32 PM +9:00, but as illustrated in the figure, it was displayed on the console as 23:22:32 +9:00, which is effectively 11:22 PM +9:00.

2. Also give me the time zone of your Graphiql Engine, Postgres server and Browser.

For the GraphiQL Engine, I have set the following environment variable: TZ=Asia/Tokyo This time zone is 9 hours ahead of UTC.

For the Postgres server, when I execute the show timezone command, it displays Asia/Tokyo.

I have not specified a time zone for the browser, but the time zone on my Mac is set to Asia/Tokyo.

3. Is your Postgres server migrated from some other timezone?

No, the Postgres server was newly set up.

Thank you @tatsuhirokasai for the detailed info. We can reproduce this issue. We are actively working to fix it asap.
As a workaround, you can remove the TZ from the Postgres database and it should work.
