941e02f Looks good.

But the ":" sign is optional according to:

time-numoffset = ("+" / "-") time-hour [[":"] time-minute]

Merged 941e02f and release 2.2.1.

I will test further possible cases with : sign. In my commit : (? in regex) is optional but there is some checking conversion after which results in a different string than input and throws an exception. I will try to think how to solve it.

Thanks for merging undefined fix.

If you are getting this error while parsing, you can use err.properText:

try {
    parser.parse(text);
} catch (err) {
    if (err.code == "INCONSISTENT_INPUT") {
        parser.parse(err.properText);
    } else {
        throw err;
    }
}
date = parser.getDate();

Instead of making Z token support :, I would suggest you to create a new token that represent timezone with :.

Indeed. I thought tokens are somewhat consistent with angular date filter but i've just noticed milliPrefix token. I agree to create a custom token for timezone with : sign. Thanks for your consultation. I will make PR during this week.
