Does Jira not have a way of enabling or allowing you to create "gaps" in the Timeline on a Epic?
It feels odd, saying you have a big project with epics, where you in February buy equipment for a new office, but the next story or "task" that has to be done does not start before April or march due to having to wait for electricity installations.
At the moment on Epic level, you can't really define saying "I plan on buying equipment from Feb 1 -> Feb 5. After that, next step wont happen before March 19.. You could "visualize this with many stories"
1: Purchase of equipment from Feb. 1 --> Feb 5.
2. Install of equipment from March 5 --> March 10.
But the "epic" will still make a timeline from Feb 1 all the way to March 10, which i understand as its project spands from this day to this end date, and work is being done within this timeline, where i would rather see some "gaps" in the timeline showing where no work is being done due to having to wait for external installations you cant do etc.
