Bug description

Issue: Report - Date format in filters not using Timestamp Format

This happens to any Date format filter.

Steps to recreate:

• Open a dashboard.
• Click 3 dots at the upper right, select Edit Chart
• Go to the Customize tab
• Select Timestamp Format: %d-%m-%Y %H:%M:%S
• Customize Columns ActivationDate and ExpiryDate uses the same date format

Actual Result:

Activation Date and Expiry Date (or any date filter) uses %Y-%m-%d format

In edit filters, theres no date format option

Expected result:

All date and timestamp fields, follow the same date format. Or can be configured.

Hi @praveer-rc! I'm Dosu and I’m helping the superset team.

This is a known limitation in Superset 4.0.2: the date format for filters is not configurable and does not use the chart's timestamp format setting. The filter UI does not expose a date format option, and the codebase confirms that filter plugins do not propagate or apply custom timestamp formats—date formatting is handled generically or via chart-level settings only.

If you need a specific timestamp format in your table/chart display, make sure no time grain is set, as time grains will truncate the timestamp and prevent full formatting from being applied. However, for filter controls themselves, there is currently no built-in way to change the date format—they will default to the standard format (typically %Y-%m-%d) regardless of your chart settings. This behavior is not patched or worked around in the current codebase, and any workaround would require custom development or forking the filter plugin components.

And which version of superset would not have this issue?

[dosubot]

There isn’t a version of Superset (including up to 5.0.0rc1) where the date format for filter controls is user-configurable or follows the chart’s timestamp format setting. The filter UI still uses a hardcoded or locale-based date format, and there’s no built-in option to change this in any recent release. This limitation is confirmed by both the code and the changelogs—any workaround would require custom development or forking the filter plugin components.

Hey, @rusackas ! Would this be a feature in any of the further releases to be able to configure the Date format of filters?
