Day arc begins. The sunflower class gazes lovingly skyward at their fire-star teacher. The newest pupils chin-strain in awe-focused attention. Reverent but energetic, their heads smooth-turn gradually westward towards their warm reward. Their blooms are a balmy destination for sunning bees. Perfect timing, rippling into the world…  

A sage watched his plants while his plants tracked the sun
He thought that it wasn’t worth noting
that petals would right to keep facing the light
as the sun-facing side was selectively dried

So sagely inquiry was done
Until the idea could receive its refloating

A physical botanist noticed the same
He took it a logic step further
His plants were all placed and completely encased
in a darkness-bound dock for a turn of the clock

The plants kept rotating their aim
And he was the first timing rhythm observer

The more he considered, the more he was sure
He could, based on solid deduction,
with confidence say that they acted this way
Through an inner intense, sunlight following sense

And urged folks to study this more
With rigours of research and science instruction

Years later, two scientists lived in a cave
A one-month foray in spelunking
Still, noiseless and lightless, the cave was all timeless
Just like the plant dock, but encased in cave rock

Their temperature curves did not change
So humans and plants had some notes to exchange…

People invent fake sunlight. Industry never stops. A timeless, tiring blur of day into night. We sit, pale and caffeinated. A world blinking fluorescent and midnight grey. A modern, diurnal nightmare. Timing battles fought from the inside…

Perched aside the optic nerve
Perfect clock inside the brain
Captured sunlight through the eye
Keeps us synched to night and day
Time and time again

Crossing zones will lead to lags
Clock and earth fall out of step
Difficult to sleep or wake
Model it to count the cost
Measured sleeping debt

Scientists find many clocks
Timing marked out body-wide
Liver, kidney, stomach, skin
Hair and muscle, pancreas
All with clocks inside

Timing cues from inside out
Hormones and adrenal glands
Exercise, consuming food
Drinking, sleeping, changing mood
Moving clockwork hands

    It’s tricky, said the shiftworker
    I’m in a real to-do
    My stomach thinks it’s ten am, my liver, half past two
    My kidneys think it’s yesterday
    My muscles Monday night
    My brain in concert with the earth, keeps timing by the light
    And all I want is sugar and a quiet kiss goodnight

Stomach, head, and heart in flux
Health and safety chrono-shock
Out of synch with social norms
Shiftworkers are precious hands
Pulled around-the-clock

Invisible clocks set with sun-travel springs
A hidden existence in all living things
