Inconsistent "CREATED" values between CLI and Docker Desktop

Bắt đầu với HumanDuration trong github.com/docker/go-units duration.go ở các dòng 28-32, sau đó theo dõi cách CLI định dạng các giá trị CREATED cho docker image ls, docker buildx history ls và docker model ls. Tái hiện các trường hợp ngày lẻ và tuần lẻ rồi so sánh chúng với Docker Desktop; hoàn thành khi các client nhất quán sử dụng hành vi làm tròn hoặc lấy phần nguyên đã thống nhất.

Description

I’ve noticed different values being shown in the CLI and Docker Desktop for the "CREATED" fields. This only occurs when the time since creation falls into days, weeks, or months, specifically when we’re partway through those ranges (e.g., 2.7 days or 3.8 weeks).

❯ docker image ls --format table
REPOSITORY               TAG       IMAGE ID       CREATED       SIZE
docker-cli-dev           latest    3ece421df299   2 hours ago   841MB
hello-world              latest    452a468a4bf9   3 days ago    22.6kB   // days: 3.958333
mcp/youtube-transcript   latest    11c974d411d7   12 days ago   323MB    // days: 12.583333

And here’s the output from Docker Desktop:

I figured out that this is a rounding issue in HumanDuration function from github.com/docker/go-units.
https://github.com/docker/go-units/blob/2d3bf9345579283aa6711d362a19f6cf222e3924/duration.go#L28-L32

I’m not sure if showing rounded values in the UI and floored values in the CLI is a deliberate choice.

Also worth noting: this isn’t limited to docker image ls. The same behavior appears in other commands like docker buildx history ls, docker model ls, etc.

Reproduce

1. Run docker model pull embeddinggemma:300M-Q8_0.
2. Run docker model ls.
3. Compare the CREATED value with Docker Desktop, or see the “Last updated” on this page

Expected behavior

We should either display rounded values on both clients, or display floored values on both clients.
