Timezone error

I found a new inconsistency. It’s about time. The date appears right (in my case with the exception of the widget) however the time always considers UTC-0.
The problems reported at this point appear to me as if they were made three hours ago. I’m in UTC-3.
I took the test at http://www.improve-my-city.com/livedemo
And I came across the same behavior.
I imagine you are in UTC-2, because the problems sent appear as if they had been done two hours ago.
This error appears only in the frontend. In admin, in the change log, the timetable appears correctly.
Can check?

Very Thanks
