<p>Upstream version 2024a released 2024-02-01T17:28:56+00:00</p>
<h2>Briefly:</h2>
<p>Kazakhstan unifies on UTC+5 beginning 2024-03-01. Palestine springs

<h2>Changes to future timestamps</h2>
<p>Kazakhstan unifies on UTC+5. This affects Asia/Almaty and

Zhanbolat
Raimbekov.)</p>
<p>Palestine springs forward a week later than previously predicted in
2024 and
2025. (Thanks to Heba Hamad.) Change spring-forward predictions to the
second
Saturday after Ramadan, not the first; this also affects other
predictions
starting in 2039.</p>
<h2>Changes to past timestamps</h2>
<p>Asia/Ho_Chi_Minh's 1955-07-01 transition occurred at 01:00 not 00:00.
(Thanks
to Đoàn Trần Công Danh.)</p>
<p>From 1947 through 1949, Toronto's transitions occurred at 02:00 not
00:00.
(Thanks to Chris Walton.)</p>
<p>In 1911 Miquelon adopted standard time on June 15, not May 15.</p>
<h2>Changes to documentation</h2>
<p>The strftime man page documents which struct tm members affect which
conversion
specs, and that tzset is called. (Problems reported by Robert Elz and
Steve
Summit.)</p>
