test/lisp/calendar/icalendar-tests.el (icalendar-convert-anniversary-to-ical):
Match new diary-anniversary/yearly-rrule behaviour.
* lisp/calendar/icalendar.el (icalendar--datestring-to-isodate): Add
year-shift option. (icalendar--convert-anniversary-to-ical): Shift
the year as diary-anniversary is not displayed in the initial year.
(icalendar--convert-recurring-to-diary): Shift the year as
diary-anniversary is not displayed in the initial year. (Bug#23100)
The test reference data was produced with accidental interference from
the system daylight saving in effect at the time. Prevent that
from occurring again and correct the data.
* test/lisp/calendar/lunar-tests.el (with-lunar-test):
Switch to UTC and make sure daylight saving adjustment is disabled.
Use normal time presentation for maintainability.

(lunar-test-phase-list): Adjust to UTC with correct times.
Enable the test by removing its :unstable mark.
* test/lisp/calendar/solar-tests.el (solar-sunrise-sunset):
Inhibit any attempt by confused calendar code to apply daylight saving
correction when Irish time zone settings are in effect. It's not
entirely clear why this is needed but may be related to the fact that
'IST' stands for both Irish and Indian Standard Time, and that Ireland
uses reversed daylight saving in winter.

(todo-edit-item--text): When editing a done item comment, prevent
clobbering match data on finishing the edit.

the date header works for intervals greater than a year, and when
incrementing or decrementing the month crosses one or more years,
adjust the year as needed.

current todo file, use it; otherwise, use the default todo file.

month validity; signal an error if it isn't. (Bug#40217)
* test/lisp/calendar/time-date-tests.el (test-days-in-month): Add
a test for the new error.
The convention in a decoded time’s dst flag is that t means DST,
nil means standard time, and -1 means unknown. This differs from
the convention for other components of a decoded time, where nil
means unknown. Fix some places where iso8601-parse mistakenly
treated nil as meaning that the dst flag was unknown.
* doc/lispref/os.texi (Time Parsing):
Adjust to match parse-time-string’s doc string.
* lisp/calendar/iso8601.el (iso8601-parse):
Set dst flag to nil if a numeric time zone or "Z" is given.
(iso8601--decoded-time): Default dst flag to -1 if no dst
flag or zone is given.
* lisp/calendar/time-date.el (decoded-time-set-defaults):
When we don’t have a time zone, set the dst flag consistently
with DEFAULT-ZONE.

(iso8601-parse-date):
Don’t bother to separate the year’s sign from the year,
as that distinction is not needed: ISO 8601 uses
astronomical year numbering with a year zero, which
is what the Emacs time functions use, so there’s no
need to treat nonpositive years specially.
(iso8601--adjust-year): Remove; no longer needed
since callers can just use string-to-number.
* test/lisp/calendar/iso8601-tests.el (test-iso8601-date-years):
Adjust test case to match fixed behavior.
* lisp/calendar/icalendar.el (icalendar--convert-ical-to-diary): Set
start time only if it is explicitly given in ical. Do not use
start-time as default for end-time (Bug#33277).
* test/lisp/calendar/icalendar-tests.el (icalendar-import-bug-33277):
New. Test fix for Bug#33277.
Instead of appending a subseconds member to the result of
‘decode-time’, this keeps the format unchanged unless you give
a new optional argument to ‘decode-time’. Also, the augmented
format now puts the subsecond info in the SECONDS element, so
the total number of elements is unchanged; this is more
compatible with code that expects the traditional 9 elements,
such as ‘(pcase decoded-time (`(,SEC ,MIN ,HOUR ,DAY ,MON
,YEAR ,DOW ,DST ,ZONE) ...) ...)’.

The list that decode-time returns now contains an extra
trailing component that counts the subseconds part of the
original timestamp (Bug#36549).

These changes remove some assumptions of Lisp code on timestamp
format. Although we’re not going to change the default format any
time soon, I went looking for code that was too intimate about
details of timestamp format and removed assumptions where this was
easy to do with current Emacs primitives.

Formerly nil meant both that DST was not in effect and that
the DST flag was unknown, and different functions interpreted
the flag differently. Now the meaning is consistently nil for
DST not in effect, and -1 for DST flag not known.

now three-valued, not two-.
* doc/misc/emacs-mime.texi (time-date): Adjust to new behavior.

* lisp/calendar/todo-mode.el (todo-add-file): Since
todo-current-todo-file must be set before calling todo-show, but
the buffer is not yet in todo-mode, which makes it buffer local,
explicitly set it buffer locally (bug#32627).
