Note that your rewrite still depends on the implicit "expr". The correct way of writing it to not depend on this implicit call would be: 
if { [expr { $n_seconds == 24 * 60 * 60} ] }

ain't none of us goin' to start writing: 

if { [expr { [string is true $foo_p] } ] }
in all of our "if" statements ...

Don, of course a Tcl if statement does an explicit expr, I never said that was bad. Most of the code I've read or written tends to use that solely to check boolean truth values though, not to do a much math, which is why I figured maybe it was a style faux paux. [shrug] Wouldn't be the first time I've been wrong.
