# Milliseconds

Milliseconds.

Package: time | Status: source-declared

Measure monotonic time, represent durations, and budget frame work.

```yh
external Milliseconds(int value) -> durationMs
```


## Use Milliseconds

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using time

// Measure monotonic time, represent durations, and budget frame work.
int value = 1
durationMs result = Milliseconds(value)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.time__milliseconds"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "time"
version = "0.1.0"
path = "../../../yeho/packages/time"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/time--Milliseconds/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
