We are currently indexing data which contains predicted values for data into the future.
I am having trouble working out how to have a real time search which will chart these 'future' predictions as they arrive.
I can chart this data perfectly as a normal search showing the chart into the future. However when I try to have this as a chart based on real time events it will only show up until now.
As the prediction data comes in we are assigning the 'prediction time' to _time.
However if I add earliest time as rt-60m and the latest time as rt+60m. Looking at the results Splunk only appears to pull the data in up to now. Not into the future as requested in 'latest time'.
Does anyone have any workarounds without me needing to convert the 'prediction time' into another field? or worse still messing with charts to handle custom times rather than _time.

Thanks for the suggestion araitz. Unfortunately showing all time in a chart would be too much data where I only need 60 minutes ago and 60 minutes into the future.
Acutally it appears to work ok in my advanced dashboard with
earliest rt-60m
latest rt+60m
I think the issue was occurring due to me being in a daylight savings state when testing and the server was set to a non daylight savings time. (Grrrr DST)
I have just tested again now that I am back in a real timezone and it appears to work as expected.
Apologies. Keep up the good work Splunk.
On a side note I spoke to a Splunk engineer yesterday and he said there was a setting in Splunk to automatically junk any data coming in that has a _time of more than 48 hours into the future.
He said that this could be disabled in one of the config files should the need arise. Seeing as I only have data a few hours into the future this is not a concern. I just thought I would mention it here if it helps someone in the future.

Using a real-time window of all-time should allow you to see all events, even those in the "future".
