It looks as though POSIX should be avoided, so I vote for (days, ticks). Is
there some reason it couldn't (shouldn't) be an opaque type? i.e. with
functions to convert to-and-from:
 - (days, ticks)
 - seconds since epoch
 - Calendar Time (in various calendars and timezones, etc)
 - other arbitrary representations
