Bug ID: 90051 Summary: Error in spec comments - g-caliio.ads (%Z) Product: gcc Version: 8.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada Assignee: unassigned at gcc dot gnu.org Reporter: bib_aab at hotmail dot com Target Milestone: --- The spec GNAT.Calendar.Time_IO, states that a picture_field with an option of "%c", will produce the following: "Sat Nov 04 12:02:33 EST 1989" The EST part is supposed to be expanded with %Z. However, the body does not support %Z and so the timezone is never shown. The relevant part from the body is: when 'c' => case Padding is when Zero => Result := Result & Image (Date, "%a %b %d %T %Y"); when Space => Result := Result & Image (Date, "%a %b %_d %_T %Y"); when None => Result := Result & Image (Date, "%a %b %-d %-T %Y"); end case; As you can see, no %Z, nor is it anywhere else in the file. The easiest fix would be to remove "EST" from the comment, however, I would prefer that the %Z field is supported.
