I also can't see any access to the internal value, so what you can do
instead is to make some time_duration, and use it instead of the absolute
ptime. Like this:

 pt::ptime epoch(greg::date(1970, 1, 1));  // or some other reference point
 pt::time_duration duration = t - epoch;
 boost::int64_t diff = duration.total_seconds(); // or total_microseconds()
or ticks()
Similarly, you can reconstruct the ptime later.
