Keyword dates search issues

I’m having issues when using keyword ranges search. What i’m trying to do is to create dashboards with today/yesterday data.

My first issue is the search input layout, it looks like this:

Second issue is probably related to timezones handling, i’m trying to do this search:

today midnight -0500 to tomorrow midnight -0500

This should get me current date timerange in eeastern timezone, that seems to work fine until the actual UTC date is matching -0500 date, after UTC goes after midnight next date the results daterange for my search switches to tomorrow as well, while it should stay on current date for 5 hrs more.

In case i’m doing this wrong, how do i achieve what i need in correct way?
