Topic: streams & file descriptors & impl defined
Relevant Sections: 8.1.1
Defect Report:
-----------------------
7. Section 8.1.1 - Extensions to Time Functions. Line 64 and line 90
are inconsistent within this section. Line 64 uses the terms 'start'
and 'end'. On line 90, the term 'date' is used. Beyond this level of
inconsistency, line 64 uses the notation for optional parameters.
Line 90 does not repeat this notation. It also does not state if the default
for no start/end date is unspecified or implementation defined. Finally, the
'rule' section does not indicate what default (or error) is
appropriate when start/end dates are omitted and 'dst' is specified.
(reference line 68).

WG15 response for ISO/IEC 9945-1:1990 (IEEE Std 1003.1-1990)
--------------------------------------------------
Line 64 is the full specification of the expanded format of a time
zone that does not have a colon as the first character.
Since no ways to determine default values for start/end date are
mentioned in ISO/IEC 9945-1:1990, the defaults are to be treated as
unspecified.
Rationale for Interpretation:
-----------------------------
The different wording used on line 90 informally re-casts the
structure of a time zone specification in a way that illustrates
one aspect of the internal logic of the syntax. There is no
conflict between the more-specific and the less-specific
statements of the syntax.
The wording of this section is being revised, in the interest
of clarity, for ISO/IEC 9945-1:1996.
