What did Time taste like?

‘There was a thought. What did Time taste like? Like didn’t and clocks and people.’

I am reading the book Sam got me for our annual Christmas Eve book gifting.

She had asked what kind of book I wanted and I told her something she read that stuck with her, or was important to her. 

She gave me two books, the first I’m reading is ‘The Martian Chronicles’ by Ray Bradbury. I’m about halfway through it and enjoying it, but this is the first quote that stood out to me.
