This section desribes the built-in function

ng:dateTimeFormat(xmlDateTime, dateFormat, part, locale, customErrorMessage)

The function converts an XML date and time (timestamp) into the format of your choice.

An alternative to this function is ng:dateFormat

This function returns a formatted date-time string and has these input parameters:

• xmlDateTime
  The date and time in the XML date-time format or just the date (format YYYY-MM-DD). If this parameter is empty (null) then the output is empty (null).

• dateFormat
  Optional input string with valid values: SHORT, MEDIUM, LONG, FULL, MASK.
  SHORT will result in the most compact output, while FULL give the most verbose output. MASK is for custom output. If not specified, then the default is SHORT.

• part
  Optional input string. When MASK is used above as dateFormat, the part must specify the mask in Java SimpleDateFormat format. For other dateFormat values, this can be DATE if you only want the date part in the output, TIME if you only want the time part in the output or AUTO for both. If not specified, then the default is AUTO.
  Possible output formats for MASK are listed here: https://docs.oracle.com/javase/10/docs/api/java/text/SimpleDateFormat.html

• locale
  An optional input specifying the locale to use when creating the string. If this parameter is not specified, then the locale setup on the template settings is used if used in a template (en-GB is used by default in the workflow).
  

  

  Note that the designer result view can only display an approximation of the actual rendered result.
  Possible values for the locale can be found on the drop down list on e.g. the Translation element.
  You can also find a list of locales here: https://www.oracle.com/java/technologies/javase/jdk8-jre8-suported-locales.html

• customErrorMessage
  Optional input which specifies the value to return, if the function cannot successfully convert the input date to the requested format (e.g. if the first parameter is not a valid date). If not specified InterFormNG2 will return the Xpath specifications.

Please notice, that ng:dateTimeFormat follows the rules of the link to the date formats above for the part paramter, so you should look out for these details:

• In the format you need to specify a capital ‘M’ for the month. (A small, ‘m’ is the minute of the hour, so you probably do NOT want that..).

• ‘E’ selects the day of the week.

• The length of identical characters sets the ‘length type’ e.g.:
  ‘E’, ‘EE’ or ‘EEE’ means ‘Fri’,
  ‘EEEE’ means ‘Friday’.
  ‘M’ means the month without preceding ‘0'.
  ‘MM’ means the month with preceding ‘0' for months 1-9.
  ‘MMM’ means the short name of the month e.g. ‘Jan’
  ‘MMMM’ means the long name of the month e.g. ‘January’.
