Deprecated locale Parameter in AuraLocalizationService JavaScript API Methods

The locale parameter is deprecated for several methods in the AuraLocalizationService object. The validation for the locale parameter has also been tightened to allow locale values to match only the user’s Language or Locale settings in Salesforce. If the locale parameter is set to another value, it defaults to the user’s Language setting.

The locale parameter has been deprecated for these AuraLocalizationService methods:

  • formatDate
  • formatDateTime
  • formatDateTimeUTC
  • formatDateUTC
  • formatTime
  • formatTimeUTC
  • parseDateTime
  • parseDateTimeUTC
