The time is in epoch format, I've generated it with this line | convert mktime(job_started_at) as time timeformat="%Y-%m-%dT%H:%M:%SZ" but I get the error Error rendering Timeline visualization: Invalid time format specified: 1574357356,1574357377,1574357421,1574357842. Supported time formats are RFC2822, ISO 8601, and epoch time which doesn't make any sense because it's literally saying "Time is in epoch, requires epoch".
Then the visualization works, but everything is in the same format. Why won't it work here? Also if I | eval time=null() then it works by placing the start of the timeline at the beginning of the search period.
