 This directory contains a suggested structure for CTS-like host-side tests for checking the
 time zone update feature has been integrated properly.
 
-These tests are not included in CTS because the OEM must perform their own integration and
-provide their own OEM-specific signed time zone data app .apks under their own package.
+These tests are not included in CTS because the OEM must perform their own feature
+integration and sign their own TimeZoneData app; no CTS-provided TimeZoneData app would be
+installable on an OEM's device.

+To pass, OEMs must provide their own OEM-specific signed time zone data app .apks under the
+correct package name and configure the test config.
