 You're supposed to get the difference in hours between your local time
zone and PST. E.g. here is what happens here:

% cat dt.cpp
#include "wx/init.h"
#include "wx/wxchar.h"
#include "wx/string.h"
#include "wx/datetime.h"

int main()
{
    wxInitializer init;
    if ( !init.IsOk() ) {
        printf("Failed to initialize wxWidgets.\n");
        return 1;
    }

    wxDateTime dt = wxDateTime::Now();
    wxPrintf(_T("Current time:\t%s\n"), dt.Format().c_str());
    wxDateTime dtPST = dt.ToTimezone(wxDateTime::PST);
    wxPrintf(_T("And in PST:\t%s\n"), dtPST.Format().c_str());
    wxPrintf(_T("The difference:\t%s\n"), (dt - dtPST).Format().c_str());

    return 0;
}

% g++ -Wall -g `wx-config --cxxflags --libs base` -o dt dt.cpp
% ./dt
Current time:   Sun Jun  3 15:58:56 2007
And in PST:     Sun Jun  3 05:58:56 2007
The difference: 10:00:00


H> But the result is 0. Probably the OS X uses internally PST?

 I'd say it's because of a bug with timezone determination under OS X :-(
It would be useful to know what does the program above output for you,
could you please run it?

 Thanks,
