Please, re-check your time zone in your profile.
Here's a screenshot:

Please note, you SHOULD set your timezone as 'default time zone' but please decrease it to "1". Server still works in past.
For example,
- Your default timezone is UTC+2. You should set UTC+1.
- And turn 'Summertime DST' button on.
