# `Tempo.Iso8601EncodeError`
[🔗](https://github.com/elixir-tempo/tempo/blob/v2.1.0/lib/tempo/exception/iso8601_encode_error.ex#L1)

A value ISO 8601 has no text for: a struct built by hand with parts in two
calendars or two zones, or a construct the notation does not write.

# `t`

```elixir
@type t() :: %Tempo.Iso8601EncodeError{
  __exception__: term(),
  reason: term(),
  value: term()
}
```
