There are different ways for different OSes. If you have access to
the hardware (DOS) you can reprogram the clock to interrupt more
often, or you can modify ada.calendar.clock to read it more
accurately. (See the replacement Calendar body I uploaded years ago
to the old Janus BBS that does the latter.) If you're unfortunate
enough to be running on such a "modern" OS as Windows, there's a
system call to get the time down to the submillisecond (see, eg, the
Ada.Calendar in RRsoftware's latest version of their Ada 95). Getting
faster interrupts is somewhat more difficult, since you need get the
OS's permission.
