Since the constructor doesn't take a string I assume you mean:

ptime(date(2002,01,20), time_duration(23,59,59));

I'm not entirely sure what you are asking to do.  Are you asking for a time
duration only?  Like this?

time_duration td(23,59,59); 

or more clearly

time_duration td = hours(23) + minutes(59) + seconds(59);

or if you really need to construct from string:

 std::string ts("23:59:59.000"); 
 time_duration td(duration_from_string(ts));

ptime is a fixed point in time and requires the specification of a date part
-- time_duration doesn't.  Hope that helps...
