Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgtype.Timestamptz represents PostgreSQL timestamptz values with Time, InfinityModifier, and Valid fields
  2. pgtype.Timestamptz implements driver.Valuer returning time.Time for finite timestamps, string literals for infinity and -infinity, and nil for SQL NULL
  3. pgtype.Timestamptz implements sql.Scanner parsing time.Time, RFC3339 strings, infinity literals, and nil values
  4. pgtype.Timestamptz implements ScanTimestamptz and TimestamptzValue for pgx native conversions
  5. pgtype.Timestamptz marshals to and unmarshals from JSON representations for finite timestamps, infinity, and null
  6. pgtype.Timestamptz encodes and decodes in text and binary wire formats using pgtype.Map
  7. sample helper functions provide structured timestamp construction, formatting, parsing, and wire conversions
