Sml.Time (SmlEx v0.1.0)

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}

Summary

t()

decode(seconds)

Decodes a parsed SML_Time term.

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

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

Decodes a parsed SML_Time term.
