Cannot use proper REV values with vCARD 3.0

[dilyanpalauzov]

In VCARD 3.0 the REV property has the format:

REV:1995-10-31T22:27:10Z

In VCARD 4.0 the REV property has the format:

REV:19951031T222710Z

For me it seems impossible to add a property of format YYYY-MM-DDTHH:MM:SSZ to using .addPropertyWithValue() as the value is always converted to the YYYYMMDDTHHMMSSZ format. But I want to create VCARD 3.0.

@dilyanpalauzov do you have a test case for this? I tried this with both 3.0 and 4.0 and it seems to simply add it with the format advised?

    let x = ICAL.parse("BEGIN:VCARD\nVERSION:3.0\nEND:VCARD");
    let comp = new ICAL.Component(x);

    comp.addPropertyWithValue("rev", "1995-10-31T22:27:10Z");
    console.log(comp.toJSON());

As far as I remember the problem was that it was not possible to specify, if the output shall be VCARD 3.0 or 4.0.

Looking at https://www.rfc-editor.org/rfc/rfc2425 section 5.8.4, it looks like vcard3 "date", "time", and "date-time" values are defined as: "value types is based on a subset of the definitions in ISO 8601 standard". The examples also provide 19960811T123456Z. REV in rfc2426 doesn't put any further restrictions on the subset, it simply says "single date-time value".

Therefore I would say YYYYMMDDTHHMMSSZ is a valid vcard3 format. Did I get that right?

It looks like we haven't heard back on this issue, therefore we are closing this issue. If this problem persists in the latest version of ical.js, please re-open this issue.
