Usage:
local Date = require('Module:DateI18n')._Date
local dateStr = Date({2020, 12, 30, 12, 20, 11}, lang)

Parameters:
* {year,month,day,hour,minute,second, tzhour, tzmin}: broken down date-time component strings or numbers
tzhour, tzmin are timezone offsets from UTC, hours and minutes
* lang: The language to display it in
* case: Language format (genitive, etc.) for some languages
* class: CSS class for the <time> node, use "" for no metadata at all
