Patch attached. (Still using %t, I don't think %m makes sense for the default.)
I don't agree with that part. When looking at sections of log files that people post on help forums, I've often wished people had shared milliseconds, and I've never wished they had truncated them off.
If two messages are separated by 0.950 seconds, it can have entirely different implications than if they are separated by 0.002 seconds.
What is the cost of using %m, other than 4 (rather compressible) bytes per log entry?
