On user profile pages, the relative timestamp such as
Member for 2 days
has exact date and time of profile creation, available on hover:
<span title="2017-10-28 20:35:56Z">2 days</span>
But if the profile was created today, this information is not available:
Member since today
(No title attribute here). This was the case with profiles created today too, but somehow got removed. Can this please be fixed?
Time of creation is most relevant for accounts created today, e.g., a wave of spam accounts.
