They are all wrong, is it just me thats affected?

Its probably with you being outside the UK.

Go to your profile (on the menu bar) then go to Preference.
At the bottom of the options there you will see the drop-down list for the timezones...so pick the one for where you are.

Let me know if that doesnt correct them x

Thanks Lisa, for some reason it had switched to Samoa time zone!

oh lol how bizarre!
