Time settings in the taskbar
I don't like the counting seconds in the taskbar, it makes me feel like time is going by too quickly. So I changed it :)
Here is how to do it:
right click on the clock on the taskbar
Clock format: %H:%M
(%R does the same thing)
Tooltip format: %A %F
This one is also a pet pieve. It does not change the way the system works (much), but it helps me to be less irritated while using Peppermint.
