"It is 10:10."
This is a tongue twister just saying jyuu ji jyuu fun with the "desu" at the end is going to take time to get fluid
I believe adding ima at the beginning is valid and doesn't change the meaning of the sentence.
It's validd but unnecessary in most cases. But if you do want to add it, don't forget to add the ha (which would be read as wa).
