Clock application

I would like to have a good and more feature-rich clock than Windows default.
It can show the time (including seconds), date and day of the week (eg Mon).
It can display times in different timezones.
A feature to copy and paste the current date &/or time is nice to have, although not really necessary.
Does anyone know if such a clock application exist?
Thank you.

If you use Firefox, you can install the FoxClocks addon:

I would like to see the clock any time, not only when I’m browsing.
Thanks a lot anyway.
