What are the ways to perform a certain action every second?

Question

C++ / C#

Let's say we have a loop:

while(true) 
{
  ... место для кода ...
}

how to set the command "if a second has passed - do an action" in it?

PS Finding milliseconds from the start of the program and checking whether they leave the remainder of the division by 1000 is not an option, the cycle will most likely "jump" the moment when the number of milliseconds is equal to the remainder of the division by 1000
