+    timezone: handle truncated timezones from tzcode-2021d and later (BZ #28707)
+    
+    When using a timezone file with a truncated starting time,
+    generated by the zic in IANA tzcode-2021d a.k.a. tzlib-2021d
+    (also in tzlib-2021e; current as of this writing), glibc
+    asserts in __tzfile_read (on e.g. tzset() for this file) and
+    you may find lines matching "tzfile.c:435: __tzfile_read:
+    Assertion `num_types == 1' failed" in your syslog.
+    
+    One example of such a file 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).
+    
+    This is valid and expected already in the published RFC8536, and
+    not even frowned upon: "Local time for timestamps before the
+    first transition is specified by the first time type (time type
+    0)" ... "every nonzero local time type index SHOULD appear at
+    least once in the transition type array".  Note the "nonzero ...
+    index".  Until the 2021d zic, index 0 has been shared by the
+    first valid transition but with 2021d it's separate, set apart
+    as a placeholder and only "implicitly" indexed.  (A draft update
+    of the RFC mandates that the entry at index 0 is a placeholder
+    in this case, hence can no longer be shared.)
+    
+            * time/tzfile.c (__tzfile_read): Don't assert when no transitions
+            are found.
