Translation:It's a quarter to seven now.
I live in Henan. I've also never heard this. I was also told by my Chinese teacher here that people don't usually say 六点三刻, for example, to say quarter past six. They always use the numbers. I often use 刻 when giving the time because it's easy, and I learned it when I studied Mandarin back in college. Some people understand me, and others ask me to repeat myself. My teacher last year said that it's more common in Taiwan.
