"Am faint o'r gloch mae e'n mynd adre?"

[WelshLadybird]

I'm confused about how this translates to "at what time does he go home?" with "faint o'r gloch"????

[EllisVaughan]

"Faint" literally means "How much", but in English we don't say "At how much of the clock does he go home?" so it becomes "At what time".
