(詳細はBig Bang theory, from the beginning of time to the end of the Dark Ages. It is a logarithmic scale that shows ''second'' instead of ''second''. For example, one microsecond is . To convert -30 read on the scale to second calculate second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the previous step.
