Subject: [Bug time/29951] New: daylight variable not set correctly if last DST change coincides with offset change
Date: Mon, 02 Jan 2023 09:51:37 +0000 [thread overview]
Message-ID: <bug-29951-131@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=29951
Bug ID: 29951
Summary: daylight variable not set correctly if last DST change
coincides with offset change
Product: glibc
Version: 2.37
Status: NEW
Severity: normal
Priority: P2
Component: time
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
The daylight variable is supposed to be set to 1 if DST is every in use for the
current time zone. But __tzfile_read does this:
__daylight = rule_stdoff != rule_dstoff;
This check can fail to set __daylight to 1 if the DST and non-DST offsets
happen to be the same.
The current tz data for Africa/Tripoli exposes this bug.
