Firefox custom date displayed incorrect

[Marvin_Rensing]

Hello, I experience a strange error when showing a custom date attribute on a metadata view. Firefox always shows January 1, 1970. I'm using the nuxeo-date element:

<nuxeo-date datetime="[[document.properties.my_schema:my_date_attribute]]" />

The strange part is, when using a default date attribute dc:created it shows the date correctly. Chromium and Vivaldi also display it correctly. Because of these facts I assume it's a bug in either nuxeo-elements or the WebUI or can I fix it somehow on my own?

Edit: The same happens with the note document and the expires date.

My setup:

Nuxeo:

• Manjaro Linux with kernel 4.15.4-2
• Docker version 18.02.0-ce
• Latest nuxeo docker image (https://hub.docker.com/_/nuxeo/)
• Addon WebUI installed

Client:

• same System
• Firefox 64bit version 58.0.2

I checked on master, 9.10 and 9.10-HF01 but I could not reproduce. Maybe your FF is not up-to-date?

FYI, for an evergreen browser, we assume users have latest versions.

I'm using FF 58.0.2 which is the latest version. Anything else I can check?
