+ * library/clock.tcl (ReadZoneinfoFile): Corrected a bug where loading
+ * tests/clock.test (clock-56.4): zoneinfo would fail if one
+ timezone abbreviation was a proper tail of another, and zic used the
+ same bytes of the file to represent both of them. Added a test case
+ for the bug, using the same data that caused the observed failure
+ "in the wild." [Bug 3470928]
