I just have the same problem, but a bit more severe since I change it and after a while, it comes back (I guess it keeps updating). Can I have a more structural solution for this?
How exactly are you going from Zotero to LaTeX? That date gets exported as date = "{2016-03-31}, in BibLaTeX and as year = 2016, month = "mar.", in BibTeX, so there's no trace of the timestamp in either.
I export the zotero to a bib file using the Better BibTex Format. In the bib file it says:
"@article{Gal2016, title = {{Abortion Pill Was Approved for Use Three Months Past Conception}}, shorttitle = {{"בשורה לנשים"}}, author = {Gal, Itay}, year = {2016-03-31T06:39:36.06636Z}, journal = {Ynet}, abstract = {מינהל המזון והתרופות האמריקני החליט להאריך את התקופה המותרת לגלולת ההפלות, מ-49 ימים אחרי הפסקת הווסת, ל-70 יום אחרי הפסקת הווסת. המשמעות: ניתן יהיה באמצעותה לבצע הפלה גם בחודש השלישי להריון. מומחה ישראלי: "בשורה גדולה לנשים"}, langid = {hebrew}, file = {/Users/tomzohar/Zotero/storage/5HE9KIZX/0,7340,L-4785472,00.html} } "
https://www.ynet.co.il/articles/0,7340,L-4785472,00.html
When I did that, it automatically put in the "Date" information the following:"2016-03-31T06:39:36.06636Z"
When I cite it on latex, it shows the following: (Gal, 2016-03-31T06:39:36.06636Z).
When I try manually to change this I can do it, but it keeps coming back to the long format probably due to some automatic syncing.
I hope this is clear.

If you have a problem with one of the built-in formats, provide an example from that.
