How to format hour and minutes in date-fns?

I'm migrating my code from MomentJS to date-fns and having the following issue when setting the hour and minutes.

This is my momentJS that works just fine:

var someDate = moment.utc('2020-07-16T16:35:39.955873Z')) // 2020-07-16T16:35:39.955Z
console.log(someDate.format('MM/DD/YYYY [ at ] LT ')); // 07/16/2020 at 4:35 PM

This is my code using date-fns:

var someTime = zonedTimeToUtc('2020-07-16T16:35:39.955873Z', 'utc'); // 2020-07-16T16:35:39.955Z
console.log(format(new Date(someTime), "MM/dd/yyyy 'at' h:mm a")); // 07/16/2020 at 10:35 AM

so, I want my date-fns code to print

07/16/2020 at 4:35 PM

but it's printing

07/16/2020 at 10:35 AM

Why is that? A simple way to get it to print the date that I want is by removing the "Z" from the value of someTime variable (like this: 2020-07-16T16:35:39.955), then it works, but I don't want to remove it manually. Can anyone tell me what I'm missing or doing wrong? Thanks a lot in advance!

Try using utcToZonedTime()

To change the displayed date/time returned from format(), you must use either:

  • utcToZonedTime: when you want to know what the local date is in another timezone
  • zonedTimeToUtc: when you want to know what a date in another timezone is in the local timezone
