This form was apparently invented by Dorian Peterson Potter.
All the poems I found were written by her, and although you can see some variance below the following seem to be the specifications.
The Egg Timer is:
A decastich (10 line poem)
Syllabic 5/4/3/2/1/1/2/3/4/5
Unrhymed
Formulaic: The last five lines are the mirror image of the first five line.
Centered or not, at poets discretion.

Learning (Egg Timer)
Learning is great fun
Just learn each day
Something new
You can
Yes

You can
Something new
Just learn each day
Learning is great fun
Right under the sun
In the moonlight
You can have
New goals
Dreams

New goals
You can have
In the moonlight
Right under the sun.
