-// Implementation of TOML's local date/time.
-//
-// Copied over from Google's civil to avoid pulling all the Google dependencies.
-// Originals:
-//   https://raw.githubusercontent.com/googleapis/google-cloud-go/ed46f5086358513cf8c25f8e3f022cb838a49d66/civil/civil.go
-// Changes:
-//   * Renamed files from civil* to localtime*.
-//   * Package changed from civil to toml.
-//   * 'Local' prefix added to all structs.

-// Package civil implements types for civil time, a time-zone-independent
-// representation of time that follows the rules of the proleptic
-// Gregorian calendar with exactly 24-hour days, 60-minute hours, and 60-second
-// minutes.
-//
-// Because they lack location information, these types do not represent unique
-// moments or intervals of time. Use time.Time for that purpose.
