Ah, of course not, since how can the default be set to the current time?

I almost always install after booting to a full OS X system on an external hard drive (so NTP syncs the time), either via a downloaded installer or after logging in to the wifi captive portal (since Internet Recovery won't do WPA Enterprise).

On Linux and Windows, the NTP update daemon "sanity checks" the new date. It refuses to update the time if the new time is "too far" from the current time. Is the Mac any different on this front?
