Use API to Get Correct Date & Time.

And Verify Device Date & Time With It.

I’ve been trying to find a solution, but there is always a problem

I will try to explain the problem better

I have an application that can run online / offline, I take time from my cell phone to set the time, like a visit,
but I have a problem that if the user delays the phone time, I change his visiting time

I can’t just check online, because he may not have internet, I can’t lock access because he has to use it without internet,
I had to find a way to know if the cell phone schedule was ahead or behind,

I can give a margin of error of 5 minutes more or less

I made this code, but there was a problem at the turn of the month, my previous tag was from the past month, when today came, it gave the problem, because
20201201+ (time) is greater than
20201130+ (time)

which definition?
date + time or time only

is this block timestamp correct?

doubt is if it is
date + time or only time in timestamp

example in php
The microtime () function returns the current timestamp in microseconds

#13

Use this block to get time in ur desired format

blocks - 2020-12-01T191423.772

#14

is it possible to transform into microseconds?

#15

Use this block to convert the time into second after then multiply the result to 1000
