If I did my time zone conversions right, it should be from 10 GMT to 12 GMT, and since I'm in GMT+1 that would be 11GMT LOC to 13GMT LOC. Or am I totally wrong??
You got it right, unfortunately Cryptic's time conversion is still based on summer time... You're best off converting from PST to wherever you are yourself, since the PST time is the most reliable one they list. In this case, you being GMT+1 means you're PST+9, making it noon for you (and most of the rest of mainland Europe, and a good part of Africa).
