# `Tempo.NonAnchoredError`
[🔗](https://github.com/kipcole9/tempo/blob/v0.5.0/lib/tempo/exception/non_anchored_error.ex#L1)

Exception raised when an operation requires a `Tempo` value
anchored to the time line (that is, carrying at least a
year component) but the caller supplied a non-anchored value.

Non-anchored values express a time-of-day axis ("every morning
at 06:00") without a specific location on the time line. Use
`Tempo.anchor/2` to compose such a value with a date before
attempting operations that require a UTC projection.

# `t`

```elixir
@type t() :: %Tempo.NonAnchoredError{
  __exception__: true,
  operation: atom() | String.t() | nil,
  value: Tempo.t() | nil
}
```
