时间 常用工具函数

dayjs 使用

import * as dayjs from 'dayjs'

dayjs(dateTime).format('YYYY-MM-DD HH:mm:ss') // 1970-00-00 00:00:00
dayjs(dateTime).format('YYYY-MM-DD') // 1970-00-00

// 搜索框使用
dayjs(startTime).startOf('day').format('YYYY-MM-DD HH:mm:ss') // 1970-00-00 00:00:00
dayjs(endTime).endOf('day').format('YYYY-MM-DD HH:mm:ss') // 1970-00-00 23:59:59
