Different time for UK/London and Europe/London about tzc HOT 1 OPEN

Hi,

Thanks a lot for reporting this. I realized that UK/London is not a valid time-zone name and one should use only Europe/London. Currently, the package does not raise an error or warn if one uses a time-zone that is not recognized, instead it returns an offset of zero from UTC. This is exactly what is happening here. I have a plan to fix this in the near future.

For the time being, I have added a very simple interactive function tzc-check-time-zone which takes a time-zone and tells whether it's recognized or not. Try using it on UK/London and Europe/London or any other name.
