Does Elastic Cloud Hosting Charge you for 24 hours in advance?

Hello everyone,

I'm quite new to the ecosystem so thanks in advance for your patience!

As the title of the post suggests I enabled the trial for the Elastic Cloud Hosting to see the features and capabilities, at first the "Billing" tab seemed to progress in a steady and predictable pace, but around 2 AM (after 4 hours of my master node being utilized) I refresh the page and see that the hours that my node was utilized jumped from 4 hours all the way up to 29 hours.

Thankfully I'm in the trial subscription, but I wanted to ask if Elastic charges you in advance for the next 24 hours that the node/component is to be utilized and if so why and under what conditions (I mean is it after 2 AM everyday or another reference point) is that?

Thanks again in advance!
