at one time

In the past

At one time means formerly or in the past: At one time, this neighborhood was all farmland.

The phrase can also mean simultaneously: The system can handle multiple requests at one time.

Context usually makes clear which sense applies—the first looks backward to how things were, the second describes concurrent action.
