Ah, because it's set up in early_time_init().

By the way, instead of avoiding NOW() early on, could we just set
local_tsc_stamp in early_time_init()? Then we could use NOW() when
initialising idle VCPUs, and also early on in init_xen_time()?

We could set stime_platform_stamp = NOW() too, so that platform time is
kicked off following BP's time.

I could send a patch which I find tasteful if you think this could work? :-)
