Codex doesn't respect 24h clock system preference on macos

Title: Desktop app ignores macOS 24-hour clock preference

Environment:

• macOS
• Time zone: Europe/Amsterdam
• macOS 24-Hour Time: enabled
• ChatGPT desktop app version: [from ChatGPT → About ChatGPT]

Steps to reproduce:

1. Enable 24-Hour Time in macOS Language & Region settings.
2. Restart the ChatGPT desktop app.
3. View a timestamp displayed by the app.

Expected: Times use system locale notation, for example 21:06.
Actual: Times are rendered using AM/PM notation, for example 9:06 PM.

The app should respect the operating system’s time-format preference. There is no separate time-format setting in the app.

Desktop app version: Version 26.1013.40934

Mac OS

Screenshot shows 9:06 PM while it should show 21:06.
