These are the iso standard timestamps I regularly use in code, which are precise but unhandy. There is no butchering, it's just one of the full standards.

As I said above it's highly unhandy to use the full string. The shortened two digits version is fully sufficient when operating in a controlled environment, because you know what each pair represents. As soon as you go into the great unknown, you can't say for sure what format is used anyway.

What we can definitely agree on, is that a standard process would help a lot, whichever it is. Preferably one that works well with alphabetically sorting.
