### Question:
BaseDateTimeLib { protected boolean timeHasOffset(String literal) { return literal.length() > 8 && (literal.charAt(8) == '+' || literal.charAt(8) == '-'); }   static final DateTimeFormatter FEEL_DATE_FORMAT; static final DateTimeFormatter FEEL_TIME_FORMAT; static final DateTimeFormatter FEEL_DATE_TIME_FORMAT; }### Answer:
@Test public void testTimeHasOffset() { assertTrue(this.dateTimeLib.timeHasOffset("12:00:00+00:00")); assertTrue(this.dateTimeLib.timeHasOffset("12:00:00-00:00")); assertTrue(this.dateTimeLib.timeHasOffset("12:00:00-0000")); assertTrue(this.dateTimeLib.timeHasOffset("12:00:00+0000")); assertFalse(this.dateTimeLib.timeHasOffset("12:00:00")); assertFalse(this.dateTimeLib.timeHasOffset("12:00:00Z")); assertFalse(this.dateTimeLib.timeHasOffset("12:00:00[UTC]")); }
