The evidence substantially and unequivocally bears out the fact that the above comment is a lie.
You said, "[...] the very nature of omniscience, noted by its definition, is atemporal [...]". And you said, "[...] I have never said atemporality is a matter of the definition of omniscience." You see Bill? You are a liar.
"Omniscience means knowing everything without respect to time."
Clearly, atemporality is a matter of the analysis based on the definition of omniscience, not the definition itself. It's not a difficult distinction to understand.
"What I am doing is defining omniscience without a time relationship because that is what it means."
You came close on this one. Here I was speaking to the nature of omniscience and since I used a form of the word "define" (define: to explain or identify the nature or essential qualities of) you took that to literally mean that this was my "official" definition. If you paid attention otherwise you would see that my "official" definition is "all-knowing".
"The omniscient being knows all without respect to time."
This is clearly not a definition.
"Omniscience is a property which is atemporal, which is say, an omniscient being knows everything at all times."
This is clearly not a definition.
"Omniscience is defined as knowing everything."
A clear statement of my definition, which matches, as far as I can find, all authoritative definitions.
"So, if the OB exists at any time, say even today, it knows everything, not just things from the past or future, but from all time. Therefore, the knowledge that the OB has is not constrained by time, and therefore, the knowledge is accurately described as atemporal."
Unequivocally, an analysis based on the definition.
"I am saying that the very nature of omniscience, noted by its definition, is atemporal, which means that all knowledge is known at all times without any ordering of that knowledge by time."
This clearly qualifies a remark on the nature (the particular combination of qualities belonging to a thing) rather than on the definition of omniscience.
Instead of trying to nit-pick through the word usage to establish of an argument and embarass yourself, go back through the last several pages and see where I explicitly said that my definition of omniscience is: all-knowing.
