-----------------------------------
Assignee: Akash Gupta
> Ranger Admin Dashboard Charts are displaying dates based on UTC Epoch instead
> of Local Time
> -------------------------------------------------------------------------------------------
>
> Key: RANGER-5704
> URL: https://issues.apache.org/jira/browse/RANGER-5704
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 2.9.0
> Reporter: Akash Gupta
> Assignee: Akash Gupta
> Priority: Major
>
> h3. *Summary*
> The charts in the Ranger Admin Dashboard are rendering data points using the
> raw UTC/Epoch time from the backend database. This leads to a mismatch
> between the chart visualisation and the actual local time of the user.
> ----
> h3. *Steps to Reproduce*
> # Log in to the Ranger Admin from a machine set to {*}PDT (UTC-7){*}.
> # Perform a policy action (e.g., Create a Policy) at 8:00 PM local time in
> Ranger Admin.
> # Observe the Policy Actions/Change count chart.
> # Result{*}:{*} The action is logged on the chart for the wrong date i.e. a
> day earlier (relative to the user's system clock).
> h3. *Expected Behaviour*
> The chart should dynamically convert the database Epoch time to the User’s
> Local Timezone (browser-based) so that the chart date reflects the actual day
> the action occurred in the user's current location.
> h3. *Current Behaviour*
> Dashboard chart data is rendered according to UTC/Epoch time. This causes
> significant confusion for users in time zones far from UTC:
> * *PDT Users:* Often see policy actions from "today" appearing on the
> previous date.
> h3. *Technical Notes*
> * Source Data: Database stores timestamps in Epoch/UTC.
> * Affected Component: All the charts related data displayed on Ranger Admin
> dashboard.
