    A wrapper for the `_formatDateTime` function which adds missing numbers.
    `_formatDateTime` uses Java APIs for formatting which don't work well with
    incomplete dates. This function takes a date from the data model and checks
    if a component (year, month, day, hour, minute, second) is missing. If the
    the component is missing the function adds uses a default value of that
    component.

    @param style The date format style from the theme manifest to use.

    @param date the date to format.

    @return The formatted date.
-->
<#function formatDateTime style date>
    <#assign year   = (date["./@year"]?size > 0)?then(date["./@year"]?number, 0)>
    <#assign month  = (date["./@month"]?size > 0)?then(date["./@month"]?number, 0)>
    <#assign day    = (date["./@day"]?size > 0)?then(date["./@day"]?number, 0)>
    <#assign hour   = (date["./@hour"]?size > 0)?then(date["./@hour"]?number, 0)>
    <#assign minute = (date["./@minute"]?size > 0)?then(date["./@minute"]?number, 0)>
    <#assign second = (date["./@second"]?size > 0)?then(date["./@second"]?number, 0)>
    <#return _formatDateTime(style, year, month, day, hour, minute, second)>
