You are only detecting negative time. But what about overflow, or if
downtime was NaN or inf?
Yeah, the test is completely wrong. It's effectively detecting only 0 time,
unsigned cannot really be negative ;)

<decimal> reminds me of base-10 integers, not floating point. It looks
like this is the first time we are accepting floating point; should we
use <float> or <floating-point> instead as the terminology?
That's probably better but this part will be removed completely in the new
version so we don't have to worry about the terminology.

Should we be using the gnulib strtod module here?
Why? It doesn't seem to be any better than C89 strtod. Or did I miss anything?
