John Stuart Mill (1806–1873) was the most famous and influential British philosopher of the nineteenth century. He was one of the last systematic philosophers, making significant contributions in logic, metaphysics, epistemology, ethics, political philosophy, and social theory.
The java.lang.System.currentTimeMillis() method returns the current time in milliseconds.The unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens ...

I guess the problem is that the timer use millis() func that shows the ms since the beginning of the program. I have no idea about how to fix this. I only need a countdown timer (I did a function) that restart from a specific value (then go till 0) whenever I call it.
Short answer: do not try to "handle" the millis rollover, write rollover-safe code instead. Your example code from the tutorial is fine. If you try to detect the rollover in order to implement corrective measures, chances are you are doing something wrong.

Aug 16, 2018· Before I begin the Arduino Millis Tutorial, let me show a simple example circuit and code that you might be following till now. Assume, Arduino UNO board and in that board, a user LED is connected to Digital IO pin 13. The following code is a simple Blink Code that Blinks the LED connected to Pin 13 of Arduino UNO.
Please note that the return value for millis() is of type unsigned long, logic errors may occur if a programmer tries to do arithmetic with smaller data types such as int. Even signed long may encounter errors as its maximum value is half that of its unsigned counterpart.

Arduino Timer and Interrupt Tutorial This tutorial shows the use of timers and interrupts for Arduino boards. As Arduino programmer you have probably used timers and interrupts without even knowing it's there, because all the low level hardware stuff is hidden by the Arduino API.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
The millis function returns the number of milliseconds that your Arduino board has been powered up. In other words, when you upload your sketch to your Arduino, as soon as the upload is complete, the clock starts. Millis returns the number of milliseconds that have passed since this upload was completed.

This method sets this Calendar's current time from the given long value.
For millis, that's approximately 49.7 days. For micros, that's 1 hour, 11 minutes, 34.967295 seconds. When computing time differences, care should be taken to handle the roll over case. An example can be found in File > Examples > 2.Digital > BlinkWithoutDelay. Internally, elapsedMillis and elapsedMicros use millis and micros.
