+Subject: [PATCH 1/3] gdatetime test: Do not assume PST8PDT was always exactly
+ -8/-7
+
+In newer tzdata, it is an alias for America/Los_Angeles, which has a
+slightly different meaning: DST did not exist there before 1883. As a
+result, we can no longer hard-code the knowledge that interval 0 is
+standard time and interval 1 is summer time, and instead we need to look
+up the correct intervals from known timestamps.

+Subject: [PATCH 2/3] gdatetime test: Try to make PST8PDT test more obviously
+ correct
+
+Instead of using timestamp 0 as a magic number (in this case interpreted
+as 1970-01-01T00:00:00-08:00), calculate a timestamp from a recent
+year/month/day in winter, in this case 2024-01-01T00:00:00-08:00.
+
+Similarly, instead of using a timestamp 15 million seconds later
+(1970-06-23T15:40:00-07:00), calculate a timestamp from a recent
+year/month/day in summer, in this case 2024-07-01T00:00:00-07:00.

+
+On recent versions of Debian, PST8PDT is part of the tzdata-legacy

+Successfully tested with and without tzdata-legacy on Debian unstable.
