Timestamps for runtime errors which display in the format of DD/MM/YYYY HH:MM:SS or something similar.

It would help both intermediate and adept programmers at logging and resolving issues while also helping in situations such as noticing patterns which aren't explicit (i.e. an error from a loop that occurs every x amount of hours).

This is especially important for commands such as -logself which displays everything in a block of barely readable text.

It's also just better for error organization.

Even an option to have it toggleable or not would go a long way too.

Oh, and, support for Linux.
