[hdf-forum] provenance

[Dougherty, Matthew T.]

thanks, Werner.

not sure what access time means, or the difference between modification time and change time.

I would guess the modified time is the latest, and previous times are not kept.

Each object in an HDF5 file should have its own "birth time, modified  
time, change
time, access time":

http://www.hdfgroup.org/HDF5/doc/RM/RM_H5O.html#Object-GetInfo

Not sure how far this is stored in the file as well; I guess an "access  
time"
would not work well for a read-only file.
