Time zone provided by yelp V3 event search API

Question

I am trying to integrate events retrieved from the Yelp API V3 . The time of the event indicated in the nodes time_startand time_endis different from the fact that they are displayed on the Yelp website. In addition, the V3 API document does not provide any time zone information, making it virtually impossible to obtain the correct time for any event.

Endpoint

https://api.yelp.com/v3/events/

{
"events": [{
    "event_site_url": "https://www.yelp.com/events/london-the-european-information-security-summit-2017",
    "id": "london-the-european-information-security-summit-2017",
    "latitude": 51.5009690970451,
    "longitude": -0.119283199310303,
    "name": "The European Information Security Summit 2017",
    "time_start": "2018-02-21 17:00",
    "time_end": "2018-02-23 02:30"
}]
}

Same event on a fork shows time as

From: Wednesday, Feb 21, 9:00 am
To: Thursday, Feb 22, 6:30 pm

I tried to configure different time intervals, but could not get the expected results.

Any help would be greatly appreciated!
