Last login date in wrong in backend

[fballiano]

In "adminhtml -> customers -> manage customers" if you click on a customer sheet and check the "last login" section, sometimes you get a weird situation like this:

the "login date" for the store timezone is correct while the UTC one is not, that is because, in the code, the formatDate function expects a "date", not a "timestamp".

After the patch, this is the result:

Manual testing scenarios (*)

Insert "2021-05-07 07:12:18" as "login_at" column in the "log_customer" table, for the user you want to test.

I guess there is another commit that fixes this issue. Please check it here #1525.

Kiatng approach seems to be much better using $useTimezone = true then UTC.

🤦🏻‍♂️ i hope it would have been merged...

anyways, the usetimezone = false should be exactly utc, but anyways this doesn't make sense.
