  22 # 1. Thousandths of a 16 hour day left. 1 = 57.6 seconds.
  23 # 2. Bar of one thousand of a day which gets shorter by ninths. One ninth is 6.4 seconds.
  24 # 3. Start of the day (only the non-zero numbers). Set this with the ds command.
  25 # 4. The time right now.
  26 # 5. Ten thousands of the year left. 1 = 52:34 minutes (leap year = 52:42)
  27 # 6. Bar of 1/10,000 of a year shrinking by ninths. 1 ninth = 5:50 minutes (leap year = 5:51 mins).
