Unless I stop the simulation, is the actual writeInterval always based on startTime?

I am trying to write data only at specific times:

(10.3, 10.55, 10.8, 11.05, ... , 12.3).

I used a 'file updating function object' method.
But the results I've got was:

(10.3, 10.5, 10.75, 11.0, ... , 12.25).

Changing the writeInterval seem to be worked properly, but the time I've changed the interval did not affected the actual saved times.

I've used the settings shown below.
Isn't it proper for my purpose?

controlDict:

~~
startFrom       startTime;

startTime       10.3;

stopAt          endTime;

endTime         12.3;

deltaT          0.0002;

writeControl    adjustableRunTime;

writeInterval   0.25;

purgeWrite      0;

writeFormat     binary;

writePrecision  8;

writeCompression on;

timeFormat      general;

timePrecision   10;

runTimeModifiable yes;

adjustTimeStep  no;

maxCo           0.2;

functions
{
    #includeFunc vorticity
    #includeFunc CourantNo
    
    fileUpdate_writeInterval
    {
        type              timeActivatedFileUpdate;
        libs              ("libutilityFunctionObjects.so");
        writeControl      timeStep;
        writeInterval     1;
        fileToUpdate      "$FOAM_CASE/system/controlDict";
        timeVsFile
        (
            (10.3    "$FOAM_CASE/system/controlDict_new")
        );
    }
