dxz0069 opened a new issue, #6695: URL: https://github.com/apache/rocketmq-dashboard/issues/6695
### Before Creating the Bug Report - [x] I have searched the [open issues](https://github.com/apache/rocketmq-dashboard/issues) of this repository and believe that this is not a duplicate. - [x] This is a defect in RocketMQ Studio, not a usage question and not a defect in another Apache RocketMQ repository. - [x] I can reproduce this on the current `rocketmq-studio` branch. ### Studio Version branch: `rocketmq-studio` git commit id: `e2f815fb` verified by: reading `InstanceService.listInstances` and the instance page renders against that commit ### Describe the Bug `rmq_instance.gmt_create` / `gmt_modified` are written by the Studio JVM (`instance.setGmtCreate(LocalDateTime.now())`, `InstanceService.java:231`) and serialize as zone-less server-local wall clocks. The instance page renders both columns with `formatDateTime` — a bare `new Date` parse, i.e. browser-local (`web/src/pages/instance/index.tsx:633` and `:645`): ```tsx {formatDateTime(d)} ``` So whenever the browser zone differs from the server zone (a UTC container deployment viewed from UTC+8), every 创建时间/更新时间 on the instance list is shown shifted by the offset — up to many hours off — while other pages that already follow the UTC-wire convention (alerts, K8s certs, and the audit/ACL tables in #6686) render correctly for the same viewer. This is the same defect family as #6679, one branch over: the instance list was not covered there. ### Steps to Reproduce Reproduced by inspection against `rocketmq-studio@e2f815fb`: 1. Deploy Studio with the server JVM/MySQL session in UTC (`TZ=UTC` is the common container default). 2. Open the instance list from a UTC+8 browser. 3. The 创建时间 column shows each instance created 8 hours later than it was (server-local `02:00` is parsed as viewer-local `02:00`, which is `10:00` server time). ### What Did You Expect to See The page should not silently reinterpret a server-local wall clock as the viewer's own. The fix direction #6686 established for the audit/ACL tables applies: convert at the JSON read path (`InstanceService.listInstances`) from the server zone to UTC and render with the existing `formatUtcDateTime`; storage stays zone-less server-local. ### Additional Context `formatUtcDateTime` and (since #6686) `parseUtcDateTime` already exist in `web/src/utils/format.ts`; the instance page just does not use them. The instance list has no CSV export, so no export path is affected. -- This is an automated message from the Apache Git Service.
