What happened?

My system's LC_TIME is set to en_GB.UTF-8. I expect all times to be in 24-hour time, yet Gemini CLI keeps showing 12-hour time.

This is visible in both the /model popup, as well as when I hit usage limits during a task.

What did you expect to happen?

I expected Gemini CLI to use my system's locale to format timestamps. I expect the model usage time to be written as Resets: 17:48 (19h 12m) instead of Resets: 5:48 PM (19h 12m).

TL;DR

The Gemini CLI may not be respecting the system's LC_TIME locale setting, causing timestamps to be displayed in 12-hour time instead of the expected 24-hour time.

Guidance

  • Verify that the LC_TIME environment variable is set correctly in the terminal or shell configuration where the Gemini CLI is being run.
  • Check if the Gemini CLI has a specific configuration option or flag to override the system locale settings for timestamp formatting.
  • Investigate if there are any known issues or limitations in the Gemini CLI version 0.38.2 related to locale settings or timestamp formatting.
  • Consider testing the Gemini CLI with a different locale setting to see if the issue is specific to the en_GB.UTF-8 locale.

Notes

The issue may be specific to the Gemini CLI's handling of locale settings or timestamp formatting, and further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Check the Gemini CLI documentation or issue tracker for any known workarounds or fixes related to locale settings and timestamp formatting, as upgrading to a fixed version is not explicitly implied in the issue.
