public void test_instant() {
Clock system = Clock.systemUTC();
assertEquals(system.getZone(), ZoneOffset.UTC);
for (int i = 0; i < 10000; i++) {
// assume can eventually get these within 10 milliseconds
Instant instant = system.instant();
long systemMillis = System.currentTimeMillis();
if (systemMillis - instant.toEpochMilli() < 10) {
return; // success
}
}
fail();
