H5Pset_obj_track_times has no effect on mtime

Hi,

I tried to use the H5Pset_obj_track_times functionality but when I want to get back the information, only change time (ctime) is filled in the H5O_info_t. The modification date is never set.
Does anyone have an experience on this feature?

I'm using HDF5 1.8.7.

Here is one example (C++) of my trial:

    H5::H5File file("c:\\TEMP\\test.hdf5");

    hsize_t dim = 2;
    H5::DataSpace dataspace(1, &dim);

    H5::DSetCreatPropList plist;
    H5Pset_obj_track_times(plist.getId(), true);
    H5::DataSet dataset1 = file.createDataSet("ds1", H5::PredType::NATIVE_CHAR, dataspace, plist );

    H5O_info_t object_info;
    H5Oget_info(dataset1.getId(), &object_info); // btime, atime and mtime = 0

    int new_value[] = {99, -13};
    dataset1.write(new_value, H5::PredType::NATIVE_INT);
    H5O_info_t object_info2;
    H5Oget_info(dataset1.getId(), &object_info2);

    dataset1.createAttribute("a1", H5::PredType::NATIVE_INT, dataspace);
    H5O_info_t object_info4;
    H5Oget_info(dataset1.getId(), &object_info4); // only ctime updated, others = 0

Thanks,
Laurent

Hi Laurent,
  Unfortunately, we haven't finished implementing all the various time features for the object info. Only the 'ctime' is set correctly and the rest will stay at 0 (until the feature is implemented).
