Hour difference between two times(HH:MM:SS a)in momentjs

Question

I have two time without date

var startTime=\"12:16:59 am\";
var endTime=\"06:12:07 pm\";

I want to show the total hours in between the abov

Answer 1

Get Hours

I got the hours by using this code

endTime.diff(startTime, 'hours')

Get Minutes

i got the minutes by using this below code

var mins = moment.utc(moment(endTime, "HH:mm:ss").diff(moment(startTime, "HH:mm:ss"))).format("mm")

My Working code is

$scope.UpdateTimeSheet = function (rowEntity) {   


            if (rowEntity.StartTime.toString().length != 11) {
                rowEntity.StartTime = moment(rowEntity.StartTime).format("hh:mm:ss a");
            }
            if (rowEntity.EndTime.toString().length != 11) {
                rowEntity.EndTime = moment(rowEntity.EndTime).format("hh:mm:ss a");
            }

            var startTime = moment(rowEntity.StartTime, "hh:mm:ss a");
            var endTime = moment(rowEntity.EndTime, "hh:mm:ss a");

            var mins = moment.utc(moment(endTime, "HH:mm:ss").diff(moment(startTime, "HH:mm:ss"))).format("mm")

            rowEntity.TotalHours = endTime.diff(startTime, 'hours') + " Hrs and " + mins + " Mns";

}
