Fixing date range to specific hours based on current date

Hello All,

I am currently working on a Kibana dashboard, which will be focused on visualizing the data for current date, except it should be fixed not to 00:00:00 but 05:30:00 instead.
So for example, right now it's 12/06/2019 16:06:00 so we would like to show data from 12/06/2019 05:30:00 to 13/06/2019 05:29:59, or basically from 12/06/2019 05:30:00 to now.
And if we launch the viz tomorrow at 08:00:00 we would like to see the following range: 13/06/2019 05:30:00 - 14/06/2019 05:29:59. It should switch dynamically every 24hours, at 05:30:01.

Is that possible?
Thanks in advance, cheers!

This is not currently possible. The date math expressions are all relative to now to provide relative dates like last month (now-1M). You can open an enhancement request at https://github.com/elastic/kibana/issues/new?template=Feature_request.md
