Hi,<br>
<br>
<br>
tzdata2024a contains (erroneously?):<br>
<br>
# Zone NAME STDOFF RULES FORMAT [UNTIL]<br>
# Beijing time, used throughout China; represented by Shanghai.<br>
#STDOFF 8:05:43.2<br>
Zone Asia/Shanghai 8:05:43 - LMT 1901<br>
8:00 Shang C%sT 1949 May 28<br>
8:00 PRC C%sT <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<br>
# Xinjiang time, used by many in western China; represented by Ürümqi / Ürümchi<br>
# / Wulumuqi. (Please use Asia/Shanghai if you prefer Beijing time.)<br>
Zone Asia/Urumqi 5:50:20 - LMT 1928<br>
6:00 - +06<br>
<br>
<br>
Shanghai refers to the rule "PRC".<br>
<br>
# Rule NAME FROM TO - IN ON AT SAVE LETTER/S<br>
Rule PRC 1986 only - May 4 2:00 1:00 D<br>
Rule PRC 1986 1991 - Sep Sun>=11 2:00 0 S<br>
Rule PRC 1987 1991 - Apr Sun>=11 2:00 1:00 D<br>
<br>
<br>
Rule PRC was only in use until 1991.<br>
Currently, in 2024, there is no rule "PRC" in use.<br>
The local time Asia/Shanghai refers to a non-existing rule.<br>
<br>
<br>
Possibly: Asia/Shanghai time currently (2024) has NO DST-rule. Similarly to Asia/Urumqi.<br>
