I set the start time of this contest as [13:30 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?msg=Nation%20Taiwan%20University%20World%20Final%20Team%20Selection%20Contest.%20dreamoon&iso=20170127T1330&ah=5&am=0). If you have no time in this time slot, don't be sad. You still can choose any time after that to enjoy the contest.↵
