Anti-time present
From Memory Alpha, the free Star Trek reference
The anti-time present was an alternate 2370 created as the result of a paradox involving an anti-time eruption formed in the Devron system in an unknown future year. In this timeline, the USS Enterprise-D was dispatched to the system near the Romulan Neutral Zone where it discovered a temporal anomaly.
The anti-time present was eliminated from the timeline when three Enterprises from three different time periods created a static warp shell within the anomaly and collapsed it. (TNG: "All Good Things...")
