I think it probably can, however only Microsoft have any expertise on 
this and they don't post here.

I strongly suspect that it would need to be an odd number, but the 
Technet definition of the registry keys doesn't say anything more about 
your 0xA setting than that it is a combination of "automatic time 
server" and "automatic reliable time server", whatever that means.  (I'm 
guessing you also need "always time server", or maybe only need it.)

Also, if you want accuracy to better than several seconds, you will need 
to set a lot more registry keys than just that one, e.g., for non-domain 
machines, the server will only be polled every 604,800 seconds.

Caution:  never run this command against a public server; it polls so 
fast that it is likely to be considered abusive.
