It's true that "amount of time" and "time" are difference concepts, but
not only can they both be represented the same way, this is widely
practiced and accepted.
In other words, and most importantly, it's not going to surprise anyone.
The key connection between the two concepts (in Unix) is "time" is
"amount of time from the epoch", and this is widely understood by
programmers (especially Unix programmers). You'll see code like this
everywhere:
time_t start;
time(&start);
*code*
printf("Time elapsed: ", time(NULL) - now);
It's the same thing.

Not at all; I don't mind defending my code. :)
