Definition: Definition: Digital, Time-Dependent Logarithmic Example in Bible: "Then God said to them, "I will make a sign between you and one another; it shall be written in your law that I have taken away the darkness from you." In the verse above, DTCLog refers to an ancient or historic method of accounting or keeping records in time. It's often associated with astronomical measurement because it's based on logarithmic scales (like logarithms on a graph). For example, if we were looking at an annual record where each year was marked by a new moon and the old moon passed through the same point in its cycle every month, then this would be an example of DTCLog.
