Timezone not displaying correctly

Since the last update of the plugin there’s an error with the conversion of the timezones, as it shows in the information an hour less than the one it might show.

In the sample page I’m adding, in the upper part of the event you see the time that might show, but in the widget on the right it’s shows an hour less, although it says it’s on GMT+1, the timezone in which is configured the server an Eventon and it’s the same as CET, but it is showing as if it was GMT time instead of GMT+1 or CET

The page I need help with: [log in to see the link]
