I used skeleton: "Bhm" to format a date.
It throwed following exception:
code: 'E_INVALID_OPTIONS',
invalidField: 'B',
type: 'skeleton',
value: 'Bhm'

My code:

var format2 = Globalize("zh-Hans").dateFormatter({ skeleton: "Bhm"})(new Date());
console.log(format2);

Could you please support 'B' in skeleton?
