My iPhone 18 months caught after my son changed the date to 1 January 1970. Apple will give me assurance, since there is no restriction in exchange for dates. What should I do ?

You can follow the instructions in this User Tip for the issue:

I set my iOS device to January 1, 1970...

Sorry, but Apple is not responsible for people following internet pranks.

Best of luck,

I wonder if it would not be a Apple's obligation to repair, because the manual is no restriction to change the date of the phone.

And what would a valid reason be for changing the date to something 46 years in the past? Did you explain to Apple what happened, as they have been taking care of devices with this error, and I've not seen anyone else report a cost involved, at least in the US.

Automobile manufacturers do not tell you not to stand in front of a moving vehicle. Common sense tells you not to. Use the same with your phone.

The phone was not "locked" intentionally. This particular malicious internet "idea" intentionally had you set the device to a date which basically was the equivalent of the beginning of time for the type of system that this device uses. Somebody with nothing better to do figured that out, and by telling gullible people to set their device to that time, they have had them set it to a date which resets the entire operating system to the moment when it was created.

This is not Apple's fault. It is a malicious prank that yielded the results that you now see. Apple will be putting in a fix that will prevent people from doing that in the future, but at this point, your child has fallen for a prank, and you are paying the price.

Follow the instructions in the User Tip provided. The only party at fault here is the jerk who thought it would be funny to con people into doing something that would render their devices useless. Blame them, and use this as a lesson for your son to not fall for everything he sees on the internet just because it's there....

Best of luck,

Your comparison of my problem with a car does not make sense. Suppose I buy a TV, I take control and put the channel 200000. My television crashes because no one will need to use the channel 20000. That would be my fault or the fault of television. This would be a logical comparison of my problem. A date change is no reason to lock a mobile phone with Apple quality.

It would be your fault

No, you misunderstand what was done. Let's take your TV comparison and put it into the correct perspective. You buy a TV and you intentionally try to put the TV to channel 200000. You cannot do it, it won't lee you, but you try to do it 3-4 more times, ignoring the fact that it wouldn't go there to start with. I say this because that is what it took to put the phone to 1/1/70. It was an intentional, malicious act, your son had to repeat several times to force the device into for no apparent reason, except that someone on the internet posted and wanted to see how many people would do it. Right next to the link that told him to do it were multiple links describing the fact that it would brick the phone, however he chose to only read the one that said to do it. Now it is time to take responsibility for his actions.
