The utcToZonedTime function adds an extra day if the timeZone parameter is "UTC" and the time portion of the passed date value is between "00:00:00.000Z" and "00:59:59.999Z".

window.console.log(utcToZonedTime(new Date('2020-02-19T18:59:59.999-0500'), 'UTC')); // Wed Feb 19 2020 23:59:59 GMT-0500 (Eastern Standard Time)
window.console.log(utcToZonedTime(new Date('2020-02-19T19:00:00.000-0500'), 'UTC')); // Fri Feb 21 2020 00:00:00 GMT-0500 (Eastern Standard Time)
window.console.log(utcToZonedTime(new Date('2020-02-19T19:59:59.999-0500'), 'UTC')); // Fri Feb 21 2020 00:59:59 GMT-0500 (Eastern Standard Time)
window.console.log(utcToZonedTime(new Date('2020-02-19T20:00:00.000-0500'), 'UTC')); // Thu Feb 20 2020 01:00:00 GMT-0500 (Eastern Standard Time)

Using date-fns-tz@1.0.9.

Looks like this issue may only happen in Chrome 80.

Had the same issue in chrome 80. Firefox and safari worked fine
Updating to version 1.0.10 solved this

We are experiencing the same issue. Is there a fix provided for the same? I see it does not work on chrome still even after I have updated the library to 1.0.10.

I've tested this with v1.2.2 and the latest Chrome and it seems to work fine now.
