A physical entity should always be displayed with its unit. Agreed in principle, but sorry, I'm not ready to install this one. Adding a unit to the value and then removing it everywhere the value is used seems error-prone to me. How about just displaying it with the unit (somehow)? Or having two values, one for the display with the unit and one without for use.
Also, I don't much want to use a new shell construct just for a cosmetic purpose like this, even if it is supposedly sufficiently portable. Which I simply doubt on principle, given our past experiences. Finally, and trivially, I think "s" would be more in keeping with what I've seen used for time units in other places (e.g., the sleep option) than " sec". --thanks, karl.
