Delphi decimal separator issue

My application works on system with regional settings where decimal separator is comma. (Delphi 10.1)

I have set dot as decimal separator for my application .

  Application.UpdateFormatSettings := false;
  FormatSettings.DecimalSeparator := '.';
  Application.UpdateFormatSettings := true;

This works fine for me.

I have used format('%6.3f', 125.365]) function. Exe is on for 24*7 on the system..

In the initial phase like 1 or 2 hours format function returns data properly with dot as decimal separator but later on it changes to local settings comma

say 12,365.

How does dot changes to comma suddenly?

get the local format setting and change it.

var
  fs:TFormatSettings;
begin
    fs:=TFormatSettings.Create(GetThreadLocale());
    GetLocaleFormatSettings(GetThreadLocale(),fs);
    fs.DecimalSeparator:='.';
end
