Question

I\'m running into a small formatting issue with moment\'s a input.

a/A will return AM/am PM/pm but is there a way to format this to include periods?

Following moment docs you can have the following:

moment.updateLocale('en', {
  meridiem: function (hour, minute, isLowercase) {
    if( hour >= 12 )
      return isLowercase ? 'p.m.' : 'P.M.';
    else
      return isLowercase ? 'a.m.' : 'A.M.';
  }
});
console.log(moment().hour(1).format('HH:mm a'));
console.log(moment().hour(15).format('HH:mm A'));

As stated in the documentation, from moment version 1.6.0

Locale#meridiem should be a callback function that returns the correct string based on hour, minute, and upper/lowercase.

While on version before 1.6.0:

Locale#meridiem was a map of upper and lowercase versions of am/pm.
