I know of no way to select dates & times by epoch - this is such an unwieldy
format for most people to use that I’ve never seen it offered in a user
interface.
Also, you cannot have different time ranges for different panels, unless this is
defined in the query for the panel, in which case it is not then selectable
from the date picker. The date picker applies to the entire dashboard, and
any panel which uses “$timeFilter” in its query will have the same date / time
selection.
However, in terms of simply selecting times, here is what I see (using Grafana
6.5.2):
-
Click on the date/time picker at the top right - when you hover the mouse
on it, it should show you the current range (with both date and time) which is
being shown. -
Once you’ve clicked on it, select “Custom time range” at the top of the
menu. -
You should see a “From” box with a month calendar underneath it, and to the
right of that, a “To” box with another month calendar underneath it, and an
“Apply” button underneath both calendars. -
Select “11” in each calendar, for 11th January 2020. You should see
“2020-01-11 00:00:00” appear in the “From” box, and “2020-01-11 23:59:59” in
the “To” box. -
You can now click onto the times and edit them to whatever you wish, for
example “17:00:00” and “18:59:59”, and when you click on “Apply”, that’s the
date and time range which will be used for your graphs.
If the above does not match your experience, let us know which version of
Grafana you’re working with, and at which point in the above steps it doesn’t
work as I’ve described.
