Writing ExifDateTime fails with an assertion error

[plampila]

Describe the bug
Writing ExifDateTime fails with an assertion error.

{ AssertionError [ERR_ASSERTION]: cannot encode {"year":2019,"month":1,"day":1,"hour":0,"minute":0,"second":0}
    at enc (...\node_modules\exiftool-vendored\dist\WriteTask.js:73:36)
...

To Reproduce

const exiftool = require("exiftool-vendored").exiftool;
const ExifDateTime = require("exiftool-vendored").ExifDateTime;

test().catch(e => { console.error(e); });

async function test() {
    try {
        await exiftool.write('test.jpg', {
            CreateDate: new ExifDateTime(2019, 1, 1, 0, 0, 0),
        });
    } finally {
        await exiftool.end();
    }
}

Environment (please complete the following information):
exiftool-vendored v8.12.0
node v10.10.0
Windows 10

Use ExifDate if you don't have time, or just set the field to a string, formatted in EXIF (2019:01:01)

I have set the time, but it still fails.

It fails even if I use ExifDate.

If it's intended to fail, it surely should not fail with an assertion error.

When using TypeScript it is not possible to use ExifDate or string without forcing it to ignore type check.

When using TypeScript it is not possible to use ExifDate or string without forcing it to ignore type check.

Agreed, that should be fixed.

[mceachen]

Note that CreateDate must be a datetime, not just a date:

 $ exiftool -CreateDate=2019:01:01 test.jpg
Warning: Invalid date/time (use YYYY:mm:dd HH:MM:SS[.ss][+/-HH:MM|Z]) in ExifIFD:CreateDate (PrintConvInv)

There are tags that allow for just dates, like ReleaseDate. I'll make sure that compiles and round-trips write/reads.

[mceachen]

Better write tag support was implemented in the newest release.

Works like a charm now, much appreciated!
