StdDateFormat (jackson-databind 2.10.0.pr2)

java.lang.Object
- java.text.Format
- - java.text.DateFormat
  - - com.fasterxml.jackson.databind.util.StdDateFormat

All Implemented Interfaces:

Serializable, Cloneable
```
public class StdDateFormat
extends DateFormat
```
Default DateFormat implementation used by standard Date serializers and deserializers. For serialization defaults to using an ISO-8601 compliant format (format String "yyyy-MM-dd'T'HH:mm:ss.SSSZ") and for deserialization, both ISO-8601 and RFC-1123.
Note that `Z` in format String refers to RFC-822 timezone notation which produces values like "-0800" -- that is, full minute/hour combo without colon, and not using `Z` as alias for "+0000".
Note also that to enable use of colon in timezone is possible by using method withColonInTimeZone(boolean) for creating new differently configured format instance.

Fields
Modifier and Type	Field and Description
`protected Boolean`	`_lenient` Explicit override for leniency, if specified.
`protected Locale`	`_locale`
`protected TimeZone`	`_timezone` Caller may want to explicitly override timezone to use; if so, we will have non-null value here.

`protected static DateFormat`	`DATE_FORMAT_RFC1123`

`protected static String`	`DATE_FORMAT_STR_PLAIN` ISO-8601 with just the Date part, no time: needed for error messages
`protected static String`	`DATE_FORMAT_STR_RFC1123` This constant defines the date format specified by RFC 1123 / RFC 822.

`protected static TimeZone`	`DEFAULT_TIMEZONE` By default we use UTC for everything, with Jackson 2.7 and later (2.6 and earlier relied on GMT)

`StdDateFormat`	`withColonInTimeZone(boolean b)` "Mutant factory" method that will return an instance that has specified handling of colon when serializing timezone (timezone either written like `+0500` or `+05:00`): either `this` instance (if setting would not change), or newly constructed instance with desired setting for colon inclusion.

`StdDateFormat`	`withLocale(Locale loc)` "Mutant factory" method that will return an instance that uses specified `Locale`: either `this` instance (if setting would not change), or newly constructed instance with different `Locale` to use.
`StdDateFormat`	`withTimeZone(TimeZone tz)` Method used for creating a new instance with specified timezone; if no timezone specified, defaults to the default timezone (UTC).

    Accessor for checking whether this instance would include colon within timezone serialization or not: if {code true}, timezone offset is serialized like -06:00; if {code false} as -0600.
    NOTE: only relevant for serialization (formatting), as deserialization (parsing) always accepts optional colon but does not require it, regardless of this setting.
    
    Returns:
    
    true if a colon is to be inserted between the hours and minutes of the TZ offset when serializing as String; otherwise false
