Hi Alexey and thanks for the feedback.

Ever since release 0.1 of coloredlogs, milliseconds have never been a part of the default log format.

I do appreciate your point that milliseconds will be shown when logging.basicConfig() is called with its default arguments. However the goal of coloredlogs is to integrate tightly with Python's logging module, not to match all of its defaults.

But looking at the workaround suggested in this issue and reading through this StackOverflow discussion I find the workaround to be rather involved, which really shouldn't be necessary (it should be easier).

I've now released coloredlogs 7.1 which supports coloredlogs.install(milliseconds=True) to make it very easy to enable millisecond precision in timestamps (it's still not enabled by default though). I've also added a section to the online documentation which mentions that millisecond precision isn't enabled by default and explains how to enable it.

I'm going to close this issue now because I'm not going to change the default in coloredlogs but I do think I've made it very easy to enable compatibility with logging.basicConfig().
