The firstboot tool asks about Date and Time settings. The accelerator key for "Next" is N (shared with all the other pages). The accelerator key for "Network Time Protocol" is also N. While here, I'll point out that Anaconda also asks for date, time, and timezone. No need to ask a second time. One of the two should probably go.
Well, you can do an anaconda install at the factory that asks, ship it to the customer, and have the customer customize it with firstboot. Or something like that.
However, the defaults aren't quite right. I carefully selected "Uses UTC" when installing and it wasn't checked when I came to firstboot. I'm not at all convinced that you should ask for the timezone twice. If you want to be able to set it at a customer site then you wouldn't bother setting it during the install. Unless it doesn't work :-)
