Hello List,

Another neophyte question (I can use some clarification): when / how are
the time-measurements (relatively speaking) designations "Ga" and Ma" used,
and their respective differences?

(I believe I know the difference through context, but why go through so many
papers and texts with the question-mark over my head?)

Sincerely,
Richard Montgomery
