 *@test
 *@bug 4848242 8342886
 *@summary Verifies that sampled European locales use consistent short time zone names.
 *         Originally assumed all European locales had the same short names,
 *         but due to changes in time zone data and locale handling, that is no longer guaranteed.
 *         This test now verifies that a representative sample of locales (e.g., fr, it)
 *         still use the same short names (CET/CEST).
