centiseconds, milliseconds, microseconds, shakes, nanoseconds, picoseconds,
femtoseconds, and attoseconds. There are separate

Experimental Countdown Timer for Multiple Unitswas created for demonstration and experimental
purposes, and it is not designed
as a practical device, but it functions perfectly, with a high level of precision.
Most of the readouts are displayed with a number of decimal places, and the
smaller units of time are displayed in scientific notation, when the numbers
are very large. When you see an e next to a number displayed by this Countdown
Timer, it means that the number is in scientific notation. For example, ‑2.79704396349e+22 PICOSECONDS, is in
scientific notation. When this number is converted to the conventional format
it is as follows:
the minus sign
on the numbers presented above. That is the readouts displayed by this Countdown Timer have
a minus sign, because it is
countdown time. However, if this device passes time zero, the minus sign is no
longer displayed, because the readout changes to elapsed time.
INSTRUCTIONS: UPDATING THE TIME
time related readouts on the Countdown
Timer are based on the time
that the device was accessed on your computer. For example, if you access the
Countdown Timer on 2/5/2014, at 12:35 PM, this time and date will not
change, unless you press the update button. The Countdown Timer also can be
updated by entering or deleting data, or by opening and closing the device.
