xclock with nanosecond (or fractional second) resolution I currently run: `xclock -digital -update 1 -strftime '%a %d %b %Y %H:%M:%S'` and am reasonably happy with the resulting xclock, but don't find it quite annoying enough. Is there any way I can add nanosecond (or decisecond, centisecond, millisecond, microsecond) precision? I tried adding a `%N` to the `-strftime` argument, but, unlike `date (GNU coreutils) 7.2`, it just gives me a literal '%N'. I don't know what version of xclock I'm running and `xclock --version` is unhelpful, but this is the version that "ships with" Fedora Core 24 if that's helpful.

`wish` of TCL can solve this readily

}

But if annoying is your goal...
