Bug 1029: typo? in specification of $? after a trap action completes  Accepted as Marked
http://austingroupbugs.net/view.php?id=1029

This item is tagged for TC3-2008

(TC2 page and line numbers)

Change page 2399, lines 76765-76766 from:
    A trap on EXIT shall be executed before the shell terminates,
    except when the exit utility is invoked in that trap itself,
    in which case the shell shall exit immediately.
to:
    A trap action on EXIT shall be executed before the shell
    terminates, except when the exit utility is invoked in that
    trap action itself, in which case the shell shall exit immediately.

On page 2420 lines 77493-77494, change:
    The value of <tt>"$?"</tt> after the trap action completes shall
    be the value it had before trap was invoked.
to:
    The value of <tt>"$?"</tt> after the trap action completes shall
    be the value it had before the trap action was executed.


On page 2420 lines 77500-77502, change:
    The environment in which the shell executes a trap on EXIT shall
    be identical to the environment immediately after the last
    command executed before the trap on EXIT was taken.

    Each time trap is invoked, the action argument shall be processed
    in a manner equivalent to:
to:
    The environment in which the shell executes a trap action on
    EXIT shall be identical to the environment immediately after
    the last command executed before the trap action on EXIT was
    executed.

    If action is neither <tt>'-'</tt> nor the empty string, then
    each time a matching condition arises the action shall be
    executed in a manner equivalent to:

Bug #1030: The Single UNIX Specification says nothing about TZ environment variable settings without alternative time start or end Accepte as Marked
http://austingroupbugs.net/view.php?id=1030

This item is tagged for TC3-2008.
An interpretation is required.

Interpretation response:
The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor.

Rationale:
If the "rule" field is not included in TZ, implementations are
required to determine when the switches between standard and
alternative time happen but were not required to document when the
transitions occur. Applications would benefit from knowing when
those transitions occur. Specifying the transition times in the
standard is not believed to be practical due to the continual changes
to time zones by legislative bodies and the potential differences
in existing implementations.

Notes to the Editor (not part of this interpretation):
On page 180 after line 5947 (XBD 8.3 TC), insert a new paragraph:
    If the dst field is specified and the rule field is not, it is
    implementation-defined when the changes to and from the alternative
    time occur.

On page 3539 after line 12001 (XRAT A.8.3 TC), insert a new paragraph:
    Implementations are encouraged to use the time zone database
    maintained by IANA to determine when daylight savings time
    changes occur and to handle TZ values that start with a <colon>.
    See RFC 6557.
