Timekeeping: Three Minutes

Is it an eternity, these 180 seconds?
Are they actually one hundred eighty degrees?
Half of a whole way around
Almost half a year
As each second silently ticks by, am I a grandfather
Clock face of rude onwardness
Forward all around, and only one twentieth of the way around
Fractions are the food of time
Eating, drinking, consuming
Subsuming the hours, minute by minute
Keeping time
In its circle
Radius
Three minutes are left
Behind the center
