Alternate timeline
(covers information from an alternate timeline)

The anti-time present was an alternate version of 2370 and 2371 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 never occurred because the three Enterprises from three different time periods created a static warp shell within the anomaly and collapsed it. (TNG: "All Good Things...")
