Surely you aren't suggesting that X servers on 64-bit platforms use a
different wire protocol than those on 32-bit platforms?

Take a look a few lines above those you quote (at least on Solaris 7,
in /usr/openwin/include/X11/X.h). It says:

/*
 * _XSERVER64 must ONLY be defined when compiling X server sources on
 * systems where unsigned long is not 32 bits, must NOT be used in
 * client or library code.
 */

And if you look in the header Xproto.h, it says:

#define Time CARD32

So, the Time fields in the X protocol are definitely always 32 bit
values.
