## Class DateTimeConverter

- java.lang.Object
- - javax.faces.convert.DateTimeConverter
  - - org.apache.myfaces.trinidad.convert.DateTimeConverter

- All Implemented Interfaces:
    javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.convert.Converter

      @JSFConverter(configExcluded=true)
      public class DateTimeConverter
      extends javax.faces.convert.DateTimeConverter
      implements javax.faces.convert.Converter, javax.faces.component.StateHolder

  `Converter` implementation for `java.util.Date` values. Converts an strings to and from java.util.Date objects.

  The converter has additonal features than standard JSF `DateTimeConverter`. New dateStyle `shortish` has been introduced. Shortish is identical to `short` but forces the year to be a full four digits. If dateStyle is not set, then `dateStyle` defaults to `shortish`.

  Timezone can be set per web-app in trinidad-config.xml configuration file. If `timeZone` is not set on the converter, then timezone will be defaulted to the value set in trinidad-config.xml configuration file. If it is not set in the configuration file, then it will be defaulted to GMT.

  The converter always allows a level of `leniency` while converting user input value to date to the following extent.

  - A converter with associated pattern 'MMM' for month, when attached to any value holder, will accept values with month specified in the form 'MM' or 'M' as valid.
  - Allows use of separators '-' or '.' or '/' irrespective of the separator specified in the associated pattern.
  - The leniency is applicable to both 'pattern' and 'secondaryPattern'.

  For example: When pattern on the converter is set to "MMM/d/yyyy" the following inputs are tolerated as valid by the converter.

  Jan/4/2004
  Jan-4-2004
  Jan.4.2004
  01/4/2004
  01-4-2004
  01.4.2004
  1/4/2004
  1-4-2004
  1.4.2004
  The detail part of faces message,for conversion errors can be customized by overriding the message associated with each CONVERT_[TYPE]_MESSAGE_ID.

  The methods used for customizing the detail message associated with each id is given below:

  1. `CONVERT_DATE_MESSAGE_ID` - `setMessageDetailConvertDate(String)`
  2. `CONVERT_TIME_MESSAGE_ID` - `setMessageDetailConvertTime(String)`
  3. `CONVERT_BOTH_MESSAGE_ID` - `setMessageDetailConvertBoth(String)`
  The custom messages can contain placeholders, which will be replaced with values as specified in its corresponding message id.

  The `getAsObject()` method parses a String into a `java.util.Date`, according to the following algorithm:

  - If the specified String is null, return a `null`. Otherwise, trim leading and trailing whitespace before proceeding.
  - If the specified String - after trimming - has a zero length, return `null`.
  - If the `locale` property is not null, use that `Locale` for managing parsing. Otherwise, use the `Locale` from the `UIViewRoot`.
  - If a `pattern` has been specified, its syntax must conform the rules specified by `java.text.SimpleDateFormat`. Such a pattern will be used to parse, and the `type`, `dateStyle`, and `timeStyle` properties will be ignored.
  - If a `pattern` has not been specified, parsing will be based on the `type` property, which expects a date value, a time value, or both. Any date and time values included will be parsed in accordance to the styles specified by `dateStyle` and `timeStyle`, respectively.
  - If conversion fails with `pattern` or `style` and if `secondaryPattern` is set, re parsers based on the `secondaryPattern`. Syntax for `secondaryPattern` must conform to the rules specified by `java.text.SimpleDateFormat`.
  - Parsing is lenient as outlined earlier and is not the same as setting leniency on `java.text.DateFormat`

  The `getAsString()` method expects a value of type `java.util.Date` (or a subclass), and creates a formatted String according to the following algorithm:

  - If the specified value is null, return a zero-length String.
  - If the specified value is a String, return it unmodified.
  - If the `locale` property is not null, use that `Locale` for managing formatting. Otherwise, use the `Locale` from the `UIViewRoot`.
  - If a `pattern` has been specified, its syntax must conform the rules specified by `java.text.SimpleDateFormat`. Such a pattern will be used to format, and the `type`, `dateStyle`, and `timeStyle` properties will be ignored.
  - If a `pattern` has not been specified, formatting will be based on the `type` property, which includes a date value, a time value, or both into the formatted String. Any date and time values included will be formatted in accordance to the styles specified by `dateStyle` and `timeStyle`, respectively.
  - `secondaryPattern` even if set is never used for formatting to a String
