Bug 795377 - Reads and saves Gnucash 2.6.19 XML file, then can't reread it, due to bad date in old file

Browse Source 
This commit contains another round of cleanups in the
timespec to time64 conversion. There were a number of
false assumptions that time64 = 0 would be a bad date
in the xml parser. This commit corrects enough of them to
eliminate the bug. Further cleanup is probably advised but
can be done at a later stage.
