While it can't rewrite history, look at NTP autokey, which can automatically 
distribute the information necessary to keep things right. ( 
http://www.eecis.udel.edu/~mills/leap-seconds.3169152000 ) Also see libtai ( 
http://cr.yp.to/libtai.html ), which does those calculations. TAI64 also fixes 
the 2038 problem.

ntp_gettime(), at least for the current time. By using libtai, the calculation 
for any given time should be trivial.
