The day is divided into 100 parts (centidays) and the time is given to three decimal places. Think of it as a percent of the day that has passed.
Mid-day will be 50.000 LMT (Local Metric Time) in metric Time.
The current time is:
How many full hours are left until the end of the year?
The Mayans used a vigesimal (or base-20) numeral system. Mayan numerals use only combinations of dots (ones) and bars (fives) to form numerals for 1 to 19, and a stylised shell glyph for zero (not shown here).
The day is divided up into 65536 parts and written in hexadecimal (base-16) notation (A=10, B=11 ... F=15). The "0x" at the begining is just to signify that it is in hexadecimal notation, we could just leave it off or use some other signifier.
Like hexadecimal time, the day is divided into 65536 parts, only we display it as a binary number using squares for bits, here using dark squares to represent 1 and white for 0.
Octal Time uses a base-8 system (digits 0-7). The day is divided into 32768 parts for a total of 5 octal digits. The right-most digit updates about every 2.6 seconds (half the speed of hexidecimal time).
Base 64 Time
Base-64 uses ASCII characters (in ascending order: A-Z, a-z, 0-1, +, and /).
Can you figure out how you would convert Base 64 time to mormal time?

Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments:
However it would be better to assign one of the student interactive activities below.
Here is the URL which will take them to a related student activity.
