Time frame or timeframe? Meaning and spelling

A time frame is the period of time in which something happens or must be done: "a time frame of two weeks". It is written time frame (two words) by most dictionaries and style guides; timeframe (one word) is common and widely accepted, especially in business. Time-frame with a hyphen is rare except as an adjective.
