An accelerated time progression today from MOMENT to YEAR, by way of common(ish) expressions all using the form "[noun] of the [time]." ORDERSOFTHEDAY (28A: Parliamentary agenda) isn't so common on this side of the briny, perhaps, but it seems to Google well enough. The Rock-OLA cross is obscure, but what else could _RDERSOFTHEDAY really be? The other three are all perfectly common. SPUROFTHEMOMENT is my favorite, because, well, I'm an impulsive person.
I'd say it's a fine start to the week.
