      Throws:
      IllegalArgumentException - if null date passed to method.

    • fromEpochMills

      public static LocalDate fromEpochMills(long dateAsMills)

    • dateTimeFromEpochMills

      public static LocalDateTime dateTimeFromEpochMills(long dateTimeAsMills)
      Obtains an instance of LocalDateTime using milliseconds from the epoch of 1970-01-01T00:00:00Z. The seconds and nanoseconds are extracted from the specified milliseconds.
      Parameters:

      Returns:
      a LocalDateTime, not null
      Throws:
      DateTimeException - if the instant exceeds the maximum or minimum instant
