The style_class for this particular field is #panel .clock-display

examples:

#panel .clock-display { color: yellow; text-align: center; font-size: 11pt; }

enter image description here

#panel .clock-display { color: yellow; text-align: center; font-size: 20pt; }

enter image description here

#panel .clock-display { color: magenta; text-align: center; font-size: 10pt; }

enter image description here

In my opinion and after several attempts,

since 1st line & 2nd line are from Clock Override Extension..
the alteration you are looking for 1st line & 2nd line is not possible unless this extension or gnome-shell system files are edited to match to separate those two lines.
