How to use the ilib/lib/DateFmt function in ilib

i18n: function () {
		// Filters used to extract the order of pickers from the ilib template
		const includeMeridiem = /([khma])(?!\1)/ig;
		const excludeMeridiem = /([khm])(?!\1)/ig;

		// Label formatter
		const formatter = new DateFmt({
			type: 'time',
			useNative: false,
			timezone: 'local',
			length: 'full',
			date: 'dmwy'
		});

		// Meridiem localization
		const merFormatter = new DateFmt({
			template: 'a',
			useNative: false,
			timezone: 'local'
		});
		const meridiems = merFormatter.getMeridiemsRange();
		const meridiemRanges = meridiems.map(calcMeridiemRange);
		const meridiemLabels = meridiems.map(obj => obj.name);

		// Picker ordering
		const li = new LocaleInfo();
		const clockPref = li.getClock();
		const meridiemEnabled = clockPref === '12';

		const filter = meridiemEnabled ? includeMeridiem : excludeMeridiem;
		const order = formatter.getTemplate()
			.replace(/'.*?'/g, '')
