How to use the ilib/LocaleInfo function in ilib

this.timeFormat = new DateFmt(format);

			const meridiemFormat = {
				template: 'a',
				useNative: false,
				timezone: 'local'
			};

			const merFormatter = new DateFmt(meridiemFormat);
			const meridiems = merFormatter.getMeridiemsRange(meridiemFormat);
			this.meridiemRanges = meridiems.map(calcMeridiemRange);
			this.meridiemLabels = meridiems.map(obj => obj.name);

			// Set picker format 12 vs 24 hour clock
			const li = new LocaleInfo();
			const clockPref = li.getClock();
			this.meridiemEnabled = clockPref === '12';

			const filter = this.meridiemEnabled ? includeMeridiem : excludeMeridiem;
			this.order = this.timeFormat.getTemplate().match(filter).map(s => s[0].toLowerCase());

			const timeFormat = {
				type: 'time',
				time: 'h',
				useNative: false,
				timezone: 'local'
			};

			if (clockPref !== 'locale') {
				timeFormat.clock = clockPref;
			}
