根据 utc 偏移量格式化日期

/**
 * @Description: 时间戳转日期
 */
export function formatTime(
  time: string | number,
  flag: any,
  utcOffset: string | null = null,
  isShowUtc = true
): string {
  const timeObj: any = {
    ymd: 'YYYY-MM-DD',
    ym: 'YYYY-MM',
    ymdt: 'YYYY-MM-DD HH:mm:ss'
  }
  let date = dayjs(Number(time)).format(timeObj[flag])
  if (utcOffset) {
    dayjs.extend(utc)
    date = dayjs(Number(time)).utcOffset(utcOffset).format(timeObj[flag])
    if (isShowUtc) {
      date += ' (UTC' + utcOffset + ')'
    }
  }
  return date
}

时长计算

/**
 * @description:  转化剩余天数格式
 */
export function switchRemainDate(millisecond: number) {
  dayjs.extend(duration)
  const days = dayjs.duration(millisecond).asDays()
  console.log('🚀 ~ file: util.ts ~ line 379 ~ getDate ~ days', days)
  return {
    time: millisecond,
    days: days
  }
}
