Anything else I have can wait until a more convenient time.

If you plan to phone in, ask the staff for a convenient time to call.

Death could not have come at a more convenient time.

I'd be able to do everything I had to, and would worry about other problems at a more convenient time.

We set a convenient time for him to phone me each day.

There's never a convenient time to leave, so we might as well just do it.
