Hm, how about supplying show_date and approxidate with current time?
Like this:

/* exported */
const char *show_date_rel(unsigned long time, int tz, struct timeval *now)
{
... the DATE_RELATIVE path of show_date
}

const char *show_date(unsigned long time, int tz, enum date_mode mode)
{
  struct timeval now;
  if (mode == DATE_RELATIVE) {
    gettimeofday(&now, NULL);
    return show_date_rel(time, tz, &now);
  }
  ... other paths of old show_date
}

Still affects the performance, but much less, and no side effects.
And you can test show_date_rel path in test-date.c
