Tests:

Moment diff to moment d
result = moment().diff(moment(d), 'hours');
Moment new Date diff to moment d
result = moment(new Date()).diff(moment(d), 'hours');
Moment Date.now diff to moment d
result = moment(Date.now()).diff(moment(d), 'hours');
Moment diff to precreated moment
result = moment().diff(m, 'hours');
e
result = moment(Date.now()).diff(m, 'hours');
Date.now minus date, division
result = (Date.now() - d) / 36e5;
moment Date.now diff to existing m
result = moment(Date.now()).diff(m, 'hours');
New Date() minus date, division
result = (new Date() - d) / 36e5;
Moment diff to moment d, divide time
result = moment().diff(m) / 36e5;
Math with moment and existing moment
result = (moment() - m) / 36e5;
Math with Date.now and moment
result = (Date.now() - m) / 36e5;
Math with new Date and m.toDate
result = (new Date() - m.toDate()) / 36e5;
Math with new Date and m
result = (new Date() - m) / 36e5;
Math with Date.now and existing moment toDate
result = (Date.now() - m.toDate()) / 36e5;
