datetimeFormat
Format for returned datetime
This is a i18n option! i18n options can not be set directly on a per-instance basis, you must include the "override" directive, and properly camel case the new name - (i.e. overrideDatetimeFormat). For more information, please take a look at the
Localizing Datebox section.
For more information on date and time format variables, see: Output Formats
Typically, this type of return isn’t based on locale, more on the format your backend is expecting. It appears in the i18n settings for ease of site-specific i18n customization.
