This is Pope Gregory's calendar reform, isn't it? I think it goes back a
century or more before 1752.

Speaking of predictability, isn't 2000 a leap year? The rule is different
for the turn of the century.
System time should be counted as the number of seconds _elapsed_ since New
Year's day 1970 (what Unix uses) or some other fixed point. These days it's
the number of seconds elapsed minus the leap seconds, which is sort of silly.
