• 当前时间 time.Now()
• 当前时间戳time.Now().Unix()
• 时间格式化string
  time.Now().Format("2006-01-02 15:04:05")
  time.Now().Format("2006-01-02")
• 时间戳格式化到string
  str_time := time.Unix(1389058332, 0).Format("2006-01-02 15:04:05")
• 今天00:00:00
  now := time.Now()
  year, month, day := now.Date()
  today_str := fmt.Sprintf("%d-%d-%d 00:00:00", year, month, day)
  today_time := time.Date(year, month, day, 0, 0, 0, 0, time.Local)
• 明天00:00:00
  tomorrow := time.Now().Add(24*time.Hour)
  year, month, day := now.Date()
  tomorrow_str := fmt.Sprintf("%d-%d-%d 00:00:00", year, month, day)
  tomorrow_time := time.Date(year, month, day, 0, 0, 0, 0, time.Local)

时间比较

• 可以转化为时间戳比较
• 也可以用before 等来比较
