The clock theming threw me off! I guess the 8 o'clock reference was just to draw our attention to PUSH. Fun effect, though, moving all the grid entries! By the way, what was the intended grid entry for the lower right corner? FAST or FIRM (if 4 letters)? or SET?
There was no intended answer for the lower right. It was meant to be ironic that the clue was about permanence and immovability yet it was simply shoved off the grid.
How do you spell the fourteenth Greek letter? Is it "chi", "xi", or "x"? Is this entry one or two more than that?
