Er, isn't that the way it's supposed to work? From man 3 snprintf -
"The value should be zero padded. For d, i, o, u, x, X, a, A, e,
E, f, F, g, and G conversions, the converted value is padded on the
left with zeros rather than blanks."
so "%02d" means print a number into a space two characters wide, padded
on the left with 0s. Which is what you are getting.
