Different time for UK/London and Europe/London

[angel-devicente]

Hi,

I just installed tzc, and while configuring it I realized that the time given for UK/London is different to that given for Europe/London, as you can see below from the tzc-world-clock command:

Canarias         09:13 Thu 12 May 2022 +0100
CET              10:13 Thu 12 May 2022 +0200
UTC              08:13 Thu 12 May 2022 +0000
New_York         04:13 Thu 12 May 2022 -0400
London           08:13 Thu 12 May 2022 +0000
London           09:13 Thu 12 May 2022 +0100
Madrid           10:13 Thu 12 May 2022 +0200

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.
