Subtraction is not working in while loop

Hi, I have encountered a very odd and annoying issue, I am writing a code that will update the previous time of a system with the current time and date. Please take a look at the following code. When I run the code, it is taking forever so I tried to debug it and found out that the values are not getting subtracted inside the while loop. It is causing the loop to run forever without stopping and giving the output. Has anybody ever faced such an issue? Is there anybody who can help me?
%Here's the Code
gps_w = 1823;
dt = 225540000;
gps_sow = 226058400+dt;
gps_sow = round(gps_sow*1000.0)/1000.0;
while (gps_sow >= 604800) %% Seconds in one week 60480
gpsw_new = (gps_sow-604800);
gpss_new = gps_w + 1;
end
while (gps_sow < 0.0)
gpsw_new = gps_sow+604800;
gpss_new = gps_w-1;
end

you didn't modify the value of gps_sow in your while loop. So the condition is always true and it will run forever. You need a gps_sow = ???. I don't understand what you are doing exactly but that's one issue.

If you do not change the value of the variable used in the condition of the while loop, this loop must run infinitly:
x = rand;
while x < 0.5
% do anything here without changing x
y = 123^2;
end
If this loop is entered, it must run forever.
Maybe you want to use if instead of while?
