### Question:
Gvl implements com.iabtcf.extras.gvl.Gvl { @Override public Instant getLastUpdated() { return lastUpdated; }  @Override int getGvlSpecificationVersion(); @Override int getVendorListVersion(); @Override int getTcfPolicyVersion(); @Override Instant getLastUpdated(); @Override List<Purpose> getPurposes(); @Override List<SpecialPurpose> getSpecialPurposes(); @Override List<Feature> getFeatures(); @Override List<SpecialFeature> getSpecialFeatures(); @Override List<Stack> getStacks(); @Override List<Vendor> getVendors(); @Override Vendor getVendor(int vendorId);  }### Answer:
@Test public void testGetLastUpdated() throws ParseException { SimpleDateFormat parser = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); parser.setTimeZone(TimeZone.getTimeZone("GMT")); Date parsed = parser.parse("2020-02-20T16:05:20"); Assert.assertEquals(parsed.toInstant(), gvl.getLastUpdated()); }
