Text content based on expression randomly glitches

I've set up a simple timer counting from 30 to 0 seconds. It works fine except the actual rendering of the numbers. Sometimes, at the end of a second, the number shifts it selves to the side before transitioning into the following one. It's a matter of 1 frame, but noticeable.
Does anybody please know how to fix it?
Thank you.

Without seeing your code nobody can tell you much. This simply looks like you are using some code that uses dynamic alignment/ padding and the internal logic is simply one frame off. Eitehr that or you are using a font that produces alternate glyphs. in the latter case you could at least try and turn these options off in the character palette. Anything else will require proper details.

Sorry for the lack of detail. 
The whole expression I'm using goes like this:

rate = -1;
clockStart = 31;

clockTime = Math.max(clockStart + rate*(time - inPoint),0);

t = Math.floor(clockTime);
min = Math.floor((t/3600)/60);
sec = Math.floor(t%60);

Compisition has relular settings, 1080p 25fps.

Get rid of the Math.max. in this context it doesn't make any sense. To convert fractional values use Math.round or use the built-in timeToFrames() method.

The Math.max() function was used to fix the final zero in place.. And even when I deleted it, the glitches remained.

Check your font as already mentioned. The code appears to work just fine.

I've tried several different fonts with various settings. Always the same result.

Truth to be said, in a completely blank, new project it works just fine even with the same font.

Is there a Tracking Animator, an animated mask, or a track matte involved?

None of the mentioned in this text layer. In terms of the whole composition, yes. But all the mattes don't interfere with this text layer.

Nope, no keyframes at all. Only the expression. But the layer is attached via parenting tool to the blue box below, after the countdown it moves to the left.
