Shortly after asking my question, I discovered that Date.parseExact() can take an array of format strings. Somehow I'm missed that. I managed to get something working with the following code:

function validateTime(input) {
    return Date.parseExact(input, [
            "H:m",
            "h:mt",
            "h:m t",
            "ht","h t"]) != null ||
        Date.parseExact(input, [
            "h:mtt",
            "h:m tt",
            "htt","h tt"]) != null;
};

Note that some formats don't seem to be able to be included together at the same time, which is why I split them into two separate parseExact() calls. In this case, I couldn't include any string that contained a single t in it with format strings that contained a double tt in it.
