# `Sml.Time`
[🔗](https://github.com/emischorr/sml_ex/blob/v0.1.0/lib/sml/time.ex#L1)

Decoding of `SML_Time`.

SML times are a choice of

  * `1` - `secIndex`, seconds since an arbitrary point (usually power on),
    decoded as `{:sec_index, seconds}`
  * `2` - `timestamp`, Unix time in UTC, decoded as `DateTime`
  * `3` - `localTimestamp`, Unix time plus local and daylight saving offsets
    in minutes, decoded as `{:local_timestamp, DateTime, local_offset,
    season_offset}`

# `t`

```elixir
@type t() ::
  {:sec_index, non_neg_integer()}
  | DateTime.t()
  | {:local_timestamp, DateTime.t(), integer(), integer()}
  | nil
```

# `decode`

```elixir
@spec decode(Sml.Parser.term_t()) :: t() | {:unknown, term()}
```

Decodes a parsed `SML_Time` term.

    iex> Sml.Time.decode([1, 1234])
    {:sec_index, 1234}

    iex> Sml.Time.decode([2, 1_700_000_000])
