使用 date-fns 库获取给定日期之间的小时数

Question

My api provides me with a "datePublished: "2019-11-14T14:54:00.0000000Z" timestamp. I want to subtract this from the current time, date.now() or new Date() and get the difference in hours. I am using the date-fns v2 library

From the date-fns docs

  var result = differenceInHours(
  new Date(2014, 6, 2, 19, 0),
  new Date(2014, 6, 2, 6, 50)
)

I am trying this:

  var result = differenceInHours(
  2019-11-14T14:54:00.0000000Z,
  new Date()
)

console.log(result) = NAN

When I use the datePublished value and the current date, I get NAN. Do I have to format the API date into a different format?

Answer 1

That's because you are comparing string with Date and not Date with Date .

Check this:

var result = differenceInHours(
  new Date('2019-11-14T14:54:00.0000000Z'),
  new Date()
)
