No, but we might use the phrase "every effort": "
I will make every effort to be there on time."

No, it's not!
I'll try my best to be on time.
I'm going to try to come on time.
Never use "on the time" like that.

In order to discover if this is acceptable/correct English, let's break it down into small phrases: I'll make Good so far.
What are you making?
all my effort
This is strange.
This claims that you have a pile of effort, and you can take from and add to it, and you're talking about the entire pile.
Alone, this is a good analogy.
However, when we look at these together: I'll make all my effort
This says that you are starting with zero effort in your pile, and you're going to make all of it.
That doesn't make much sense.
A better alternative is use or give instead of make .
Let's move on to the rest of the sentence: to come Alight
, that's okay.
To where are you coming? on the time
Here's where it gets silly.
This makes it seem like you're starting where you are, and your destination is "the time".
Also, "to come on" has a rare, but lewd definition (see Wiktionary's 5 th verb definition ), so you shouldn't say you come on something.
So what is a good alternative to to come on the time ?
Well, let's go back.
to come was fine, and I asked "To where are you coming?".
Let's answer that with in .
"Where are you coming?"
"I'm coming in!"
Now I can ask "When are you coming in?", and you can answer with on time , meaning that when you come in, it will be at the correct time.
Putting it all together, here's what you probably want to say: I'll give all my effort to come in on time.
Perfect!
You've got a pile of effort, and you're giving all of it in your attempt to go from where you are to here at the correct time.

No.
A better way to say it would be 'I will do my best to be on time'

You could also use "best efforts" "I'll make best efforts to come on time"or"I'll make my best efforts to come on time"

If I say:    I'll make " all my effort " to come on the time"   Is it considered an acceptable / correct English?
I'll make "all my effort" to do that - acceptable idiom?

That would not be correct, but you might say "I will  do my best  to be on time", "I'll make my best effort to be on time", "I'll try my best to be on time" or "I'll make every effort to come on time". All the effort' and 'on the time' are incorrect. You could say 'I will try/do my best to be on time' or 'I'll make best efforts to be on time'.
