If I run:

last -t 20150101010101

I still get logins displayed (even though the date is in the future)

If I run

last -t 20140723123000

I still get logins displayed from months back.

I would expect to only see logins from earlier on today. Is this correct?

from man last: -t, --until time --> Display the state of logins until the specified time., so the output you are getting makes sense. – fedorqui Jul 23 '14 at 13:30

last -t YYYYMMDDHHMMSS shows the status of the login files up to the date specified, rather than since the date specified.
