I do only work that I actually like. (Yet. Soon it will change ) So, besides that the making the script was kind of fun for me, it saves me from breaking off from other fun .
(And I think you couldn't write such a script even if your computer skills were less forgotten. I'm afraid I used rather different things you were used to use. (Every programmer nowadays knows the Epoch, or the launch of the first Unix system, and that's 1. I. 1970, 0:00 GMT. The tools I used now have their origin in those times ... but I think you took a rather different way when you were learning computer stuff...))
