Set the time zone to London and change time to London time. You can update the time first when you connect to the wireless internet (not yet configuring tor), once that is done you can connect without any problem. If there are problems, try -1 hour or +1 hour to account for daylight savings depending on your area. Mine was -1 and worked well. 

You can also edit the `iat-mode=0` to `iat-mode=1` or `iat-mode=2`.

Good luck.
