Oh, I see. '' + arLastLoginDate will force JavaScript to convert arLastLoginDate to a string.
Have you debugged the JavaScript to see what value it is actually submitting to the API? You can do this in most browsers by opening developer tools (F12) and going to the Net tab. You should see the post made by jQuery, and be able to read the raw data. You'll want to make sure that URL and the data are valid.
Yeah, it looks alright. Funny thing is, I switched to a user where it wasn't writing and it wrote this time.
It seems to be specific to where the user is, maybe what browser they're using, or something..
