This is cutesy, but having a timestamp on your prompt is an easy-to-implement sometimes-lifesaver. Highly recommended, one way or another :)

Speaking of another:

    export PS1="\t $"

For a lot more information on bash prompts, I'd recommend http://blog.sanctum.geek.nz/bash-prompts/

Out of curiosity, could you describe a scenario where you'd consider time-stamping like that to be a lifesaver?

I'd love this for its compact nature, but I like digital for its precision. A title tag would be great!
