I don't think there's anything wrong with this format, it looks good. The most important thing for nerdlog is that all components of the timestamp must be at the fixed offsets from the beginning of each line. So I believe it can be implemented, I can look at it on the weekend. Feel free to create an issue on Github (I won't be able to test it for real, so would need your help with that)
