Time is represented in an unusual way in Bolandia. The format is mm:hh, where mm represents the number of minutes to the next hour (hh). For example, 17:03 represents 17 minutes before 3am. However, there are still 60 minutes in an hour and 24 hours in a day. Helen is staying in a hotel in Bolandia, and the clocks in the hotel display time in this way. When she goes to bed one evening, the clock in her room reads 21:23. She wakes up a while later and sees that the clock says 23:04.
