timezone: test-case for BZ #28707
|
||
|
|
|
||
|
|
This test-case is the tzfile for Asuncion generated by
|
||
|
|
tzlib-2021e as follows, using the tzlib-2021e zic: "zic -d
|
||
|
|
DEST -r @1546300800 -L /dev/null -b slim
|
||
|
|
SOURCE/southamerica". Note that in its type 2 header, it
|
||
|
|
has two entries in its "time-types" array (types), but only
|
||
|
|
one entry in its "transition types" array (type_idxs).
|
||
|
|
|
||
|
|
* timezone/Makefile, timezone/tst-pr28707.c,
|
||
|
|
timezone/testdata/gen-XT5.sh: New test.
