at a time
at once **
at one time

Cases are held at different times to any other case being heard by the court on the day.

At other times I would not do such a thing.

How do you get your news at different times of the day?

At times, he looked for the open man more than his shot.

And sure, he did go over the top at times.

Yet even now he found himself thinking of the problem at times.

At times, he is so good, the position does not seem to matter.

They come and go at different times of the day.

But now I feel no different than at other times of year.

And at other times I could see but couldn't hear.
