The end of time is here! That is if you are using a 32-bit system, which at this point, in 2025, you really should not be using… Right?

So why does the 32-bit implementation of Unix time end at this specific time? It all comes down to mathematics.

Unix Time is using a signed 32-bit integer to store the time and the highest positive value a signed 32-bit integer can have is 2³¹ -1 or 2147483647. Looking at this number in a binary format gives us a better explanation. In binary, the number 2147483647 would be stored as 11111111 11111111 11111111 11111111 and if you try to increase the number by one, you would get 10000000 00000000 00000000 00000000. This, according to the “two’s complement” (a mathematical operation on binary numbers) way of storing numbers, would be -2147483648 or -2³². The computer simply goes from thinking it is 2147483647 seconds after the start of Unix Time in January 1, 1970 (January 19, 2038) to thinking it is 2147483647 seconds before January 1, 1970 (December 13, 1901).
