This is a charade - multiple separate components are placed one after another to build the final answer.
Break down each part: 'approaching' gives you the first word, 'tenses' provides two T's, 'one' and 'male' each contribute single letters, and you need the final letter from 'alone'. String all these components together.
Answer: NIGHTTIME | NIGH (approaching) + T + T (two 'tenses') + I (one) + M (male) + E (end of 'alone')
