What this solution does
The module combines the Date and String user property types into a single unified property. Two display variants are available: "Date / String" and "String / Date". The property can be used as a user property of the main module or as a property of an information block element.
To customize the display of the main module's user property, edit the following files:
/bitrix/templates/.default/components/bitrix/system.field.view/CDenwistDateStringType/template.php
/bitrix/templates/.default/components/bitrix/system.field.view/CDenwistStringDateType/template.php
The display of an information block element property depends on the component utilizing that property.
