Following an update to waybar, the clock starting displaying fractional
seconds. Changing seconds from `%S` to `%OS` truncates the fractional
second, though this is possibly not portable as `%OS` is "alternative
second display" and the definition of "alternative" is vague.
I apparently forgot to do this ever. I've been using this for about two
months now.
I just reused the modules I built for my swaybar, which already output
close to the proper format; now I just call the modules directly with `if
__name__` hooks to output Waybar format instead of Swaybar format.
