You would need to build on the fly the INI file, to use the
"Define=foo=44" capability (not available from the command line) to set
the value of variable foo to 44. (should work with 3.7 version, at least)

Either that, or you create also on the fly some file that get #include
by your main script. Content of such file could be "#define foo=44;"

Now, if all you have to set is just one single parameter (and not a
collection of them), you can instead use the animation sub-system to set
the clock value,
look at +K, +KI, +KF, +KFI, +KFF, +SF, +EF, +KC vs -KC
