moment().subtract('days', 7); 减7天
moment().add({days:-7,months:1}); 加1月，减7天
2.2设值
moment().seconds(30); year/month/date/day/minutes/seconds 方法
moment().seconds(); 取值
设首/尾
moment().startOf('year'); // set to Jan 1 12:00:00.000 pm this year
moment().startOf('month'); // set to the first of this month, 12:00:00.000 pm
moment().startOf('day'); // set to 12:00:00.000 pm today
moment().startOf('hour'); // set to now, but with 0 mins, 0 secs, and 0 ms
moment().startOf('minute'); // set to now, but with 0 seconds and 0 milliseconds
moment().startOf('second'); // same as moment().milliseconds(0);
moment().endOf('year');
moment().sod(); 当天头
moment().eod(); 当天尾
