Date

The jp:outputDate can be used to format dates to various output patterns which are defined in AppSettingsBean. The allows a single place in the whole application to configure date patterns and control them with the attributes

withDate (default=true)
withMinute (default=false)
withSecond (default=false)

Please note that the patterns has to match the datatype of the binding value, e.g. a LocalDate with a time pattern will throw a "Unsupported field: HourOfDay" exception.

The type attribute controls the converter implementation and is responsible to handle the new Java 8 (java.time.*) data types.

java.text.SimpleDateFormat : date, time or both
java.time.format.DateTimeFormatter : localDate, localTime, localDateTime, offsetTime, offsetDateTime or zonedDateTime

Since the pattern in JEESL is fully controlled via different pattern definitions in AppSettingsBean, it's only required to use

type= both (Java 7, needs to explicitly be set)
type= localDate (Java 8, default setting)
