// Description:

// Clock shows h hours, m minutes and s seconds after midnight.

// Your task is to write a function which returns the time since midnight in milliseconds.

// Example:
// h = 0
// m = 1
// s = 1

// result = 61000
// Input constraints:

// 0 <= h <= 23
// 0 <= m <= 59
// 0 <= s <= 59


// My Solution:

function past(h, m, s) {
  return h * 60 * 60 * 1000 + m * 60 * 1000 + s * 1000
}
