The 7 bowls of wrath

No.

This would necessitate the anti-christ has come to power and made his mark available as well as a revealing of the image of the beast. None of this has come to pass yet, and so the time of the seven bowls of wrath is not yet.

That's what the Book of Revelation says.

The "clear distinction" is basically the time of the Tribulation (meaning the seven years including the 3.5 years called "the beginning of sorrows, and the 3.5 years called "the Great Tribulation" after the anti-christ comes to power). All of the events attributed to "end times" fall during this period. Any other fear-mongering outside this period (even if they call it "end times" ) has no effect upon the outcome, and, frankly, is basically just people trying to sell their book.
