However, please also note that it should be possible to easily just make the accuracy arbitrary. It's printed out in a format that is meant to be scannable by "%f", so if you want to make it contain a few hundred significant digits then you could..
Always having microsecond resolution is a bad idea. Because something is bound to come along that wants nanoseconds. So if you just basically say that any fractional amount should always be printed out as a floating point number, then you're fine.
(Obviously you don't actually want to use fp math inside the kernel: printing out numbers in a fp format does _not_ imply using actual fp arithmetic. The code does it all with integer arithmetic right now).
