# TaskTotal

Task total.

Last updated: 2026-09-09

Package: time | Status: source-declared

Tags: cpu, function, task, time, timing, yeho

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

```yh
external TaskTotal(task of int handle) -> durationMs
```


## Measure a completed task

Measure a finished score calculation. Durations vary between runs.

Verification: executed

```yh
using time

Score() -> int { return 40 + 2 }
task of int job = task Score()
wait job
durationMs elapsed = TaskTotal(job)
Console.Log(elapsed.AsText())

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

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

```

Executed backend: cpu-oracle

Observed output:

```text
duration
```

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--TaskTotal/complete --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.
