I always was able to hold on to the orignall calibre libaery database but had to reload books to the Ipad (due to changing of device or reader apps) multible times, and therefore alwayse lost the time sorting function!

I did some follow-up experiments on calibre after my reply in
post #89. Unfortunately, the update time-stamps cannot really be used as a proxy of "Date/Time Added". Even a minor change, such as the series number, on ONE book is sufficient to cause the update time-stamps of ALL books to the present time. Thus, you still won't get anything close to what you want--original Date Added to calibre.
There is nothing wrong with calibre per se, as the update time of each entry in any OPDS catalog (generated by calibre or not) is not necessarily the last modification time.
If you do want this feature badly enough, I do have a suggestion. Talk to the calibre developers (active on mobileread.com) and suggest them to include the value of the "Date" field of each book as part of its corresponding OPDS entry. As far as I know, this field is not part of the OPDS standard, but they have already done something similar for Tags, Series and Number by embedding them inside a standard <content> element.
Note that this suggestion is not app-specific. If there are enough calibre users who express their common wish for this feature AND calibre supports it in the future, BookMaster will support it too.
thomasmorus, please start another thread in calibre forum if you like to do so. Thanks.
