GMT+2 (until 31 October, when it switches to GMT+1)
Gdańsk, Poland
Times differ each day, not to mention some laboratories/projects that happen each second week. Generally I'm always at home between 18 and 5 GMT, including the time I'm usually asleep, and sometimes I might be able to fight while in University's library, though that might become easier if/when I manage to fix my laptop (I used to play during lectures) ;]
We can always try to use goodies like
http://whenisgood.net/or google calendar, or whatever
As for excel file, you can probably attach it to your post, but displaying it inside the page like SG does probably requires administrator's privileges.
