Right. I assume you were *very fast* typing in that data and that
seconds did not move on while you were doing it. :-) I get the point
though. That value is a timezone independent value.

I think something was lost in translation.
date '+%Y-%m-%d %H:%M:%S'
That will always produce the current time. That means that
date +%s -d "`date '+%Y-%m-%d %H:%M:%S'`"
is always the same as
date +%s
There is no need to call date twice to get that result.
Please say a few more words about what you are trying to do. I think
with a little more understanding it will make better sense. I see
that you are trying to produce a unix seconds epoch based upon some
time but creating it with date doesn't do it. You would need some
other time.
date +%s -d 'last thursday'
