Stat cleanup.
Put global stat info in a union so we don't have to malloc it and thus don't need an explicit size tracked in main(). Make date_stat_format() take a timespec and take advantage of stat having an embedded timespec (nanosecond printing), typecast the long long prints for XYZ because on some 32 bit platforms it's an int.
