I mean: In the context of octets zero-padded may mean binary zeroes, and not '0'.

That's how I interpreted it.

<tp>
Yes. Going back to RFC958, it has

'     Code identifying the particular reference clock. In the case of
      type 1 (primary reference), this is a left-justified, zero-filled
      ASCII string identifying the clock, for example:

         WWVB    WWVB radio clock (60 KHz)

         GOES    GOES satellite clock (468 HMz)
         WWV     WWV radio clock (2.5/5/10/15/20 MHz)
         (and others as necessary'

I assume that if the digit '0' had been intended, then it would have listed 
WWV0 and not WWV.  A later RFC has a reference to RFC1345 for ASCII character wthout qualification which suggests that there was no constraint intended to just capital alpha ASCII.
