Time fractions
This activity belongs to the GeoGebra book The Domain of the Time.
However, the simplest way to record time is to use the clock on the device we are using (computer, mobile, etc.).
The command GetTime() allows you to collect the real date and time from the computer or device you are using. When executed, it returns a list that begins with the current time in the following order:
{milliseconds, seconds, minutes, hours, date, month, year, month (text), day of the week (text), day of the week}
For example, if it is currently 3:09 a.m. (with 45.347 seconds) on January 6th, 2024, it will return:{347, 45, 9, 3, 6, 1, 2024, "January", "Saturday", 7}
In the following activities, you only need to consider the first three elements of this list. In this activity, you can choose to use the current time collected by this command or set the time freely as you wish. In the latter case, you can move the ends of the three hands to set the clock to the desired time. It is recommended to follow this order: hour hand, minute hand, second hand. You can also automatically animate the freely set time simply by choosing the animation speed (if you do not want this animation, select a speed of zero). Regardless of the type of time chosen, you can stop the animation at any moment (small button in the lower left corner). You can also activate the chronometer at any time, but keep in mind that the chronometer will always record the real time, in seconds, elapsed between its activation and stoppage.Author of the activity and GeoGebra construction: Rafael Losada.
