That's because you're using substr() incorrectly.  Try the following:

	$ANYAWK 'BEGIN {print substr("12:", 1, 2); }'


Note the definition (from "The One True AWK" manual page):

       substr(s, m, n)
              the n-character substring of s that begins at position m
              counted from 1.

As far as I can remember all AWK strings are counted from 1, not zero,
though it seems only the real AWK manual is careful enough to say this
explicitly for substr().
