    Nope. They’re both totally wrong. Even pm (or am) with o’clock is wrong.

    6 o’clock [in the evening] :tick:/ 6 pm :tick: / 18.00 :tick:

    "O'clock" is only used with 12-hour notation.

    If you need to pronounce 18:00, then either convert it to 12-hour format ("six pee em" or "six o'clock") or else use "eighteen hundred hours".
