The word "Panahon pa ng Kopong-kopong" is a Tagalog phrase which means "a very long time ago." The origin of the term "kopong" is an old Tagalog word for zero, so technically speaking, Panahon pa ng Kopong-Kopong means 1900 and note the two "00" or "kopong."
"Panahon pa ni Mahoma" means the time of Muhammad, the prophet of Islam. Mahoma is an alternative spelling of Muhammad's name.
Yet, there are others who say that Mahoma means the Japanese General Masaharu Homma. So Panahon pa ni Mahoma means a time somewhere in the early 40's during the Japanese occupation of the Philippines.
