times news events

Hello. There is a problem with the times of the news events in Forex tester online . I made a chart with UTC+2. I live in the Netherlands where it is time GMT+2. I think UTC+2 = GMT+2, right?? When check the news events in Forexfactory.com (I adjusted it to GMT+2 in the upper right corner) it is not corresponding with the news event times in Forex tester online. For example I checked 4 January 2023. There is a US news event according to forexfactory on 16:00 (04:00 pm). But in Forex tester online it shows on 17:00 (05:00 pm). When I made the chart I used UTC+2 plus European DST and also selected NO DST. I don’t understand why GMT cannot be selected in Forex tester online. I tested with making alot of charts and playing with these settings. Maybe I do something wrong and hopefully there is a solution so I can backtest and improve my bad trading.

. I will add some screenshots.
