# `Tempo.FloatingTempoError`
[🔗](https://github.com/elixir-tempo/tempo/blob/v1.6.4/lib/tempo/exception/floating_tempo_error.ex#L1)

Exception raised when an operation requires zone or offset
information but the supplied `Tempo` value is floating — no
`[IANA/Zone]` tag, no `Z`, no numeric offset.

Floating values are deliberate (see the scheduling guide) but
cannot be projected to UTC, so any operation that needs a
universal instant rejects them.

# `t`

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