Additional date/time formats are now introduced in `java.time.format.DateTimeFormatter/DateTimeFormatterBuilder` classes. In prior releases, only 4 predefined styles, i.e., `FormatStyle.FULL/LONG/MEDIUM/SHORT` are available. Now the users can specify their own flexible style with this new `DateTimeFormatter.ofLocalizedPattern(String requestedTemplate)` method. For example,
```
DateTimeFormatter.ofLocalizedPattern("yMMM")
```
produces a formatter, which can format a date in a localized manner, such as "Feb 2022" in the `US` locale, while "2022年2月" in the Japanese locale. Supporting method `DateTimeFormatterBuilder.appendLocalized(String requestedTemplate)`is also provided.
