in these times; "it is solely by their language that the upper classes nowadays are distinguished"- Nancy Mitford; "we now rarely see horse-drawn vehicles on city streets"; "today almost every home has television"
the period of time that is happening now; any continuous stretch of time including the moment of speech; "that is enough for the present"; "he lives in the present with no thought of tomorrow"
