Ask HN: What small library or tool do you want that doesn’t exist?
I sometimes find myself wanting a Unix timestamp, or to convert one into a human-readable date, and usually it&#x27;s simpler to go to an online tool than use time(1).<p>It might be nice to have a command line tool which can guess from the arguments what you want it to do.  For example, if you run it with no arguments, it would output the current timestamp (to multiple levels of precision, listing the languages&#x2F;platforms that typically use each one).
