If I correctly understand the question about the related problem
it is a lack/fault the missed incoming *local time* (because, for me,
using the *time zone* may be a bit confusing) in the index file.

If so, the 'local date' and the 'local time' (i.e. the incoming 'local time'
read on our machine) should be implemented.

As shown below, for the same msg received in xfbb and in JNOS2,
note that the JNOS2 reports even more data with respect to xfbb
when we read the message in verbose mode.

Now, concerning the expire process, the JNOS2 'expire.dat', like to
the other counterpart 'epurmess.ini' in (x)fbb, express the expiration
time is in Days, but the effective expiration/deletion may/should
happen *only* after the 'days+localtime' incoming date.

Then, even if the system receives today a msg with a wrong
original date, say December 25, 2015, but the real incoming
Date/Time is 1115/0435 (local) is registered on our index file,
then if I setup 10 days to expire that kinda message, it means
that the expiration date would be possible only after the real
1125/0435 (local) date.

On the other face of the medal, assuming the 10 days setup for
our message area, if the system receive a msg more old of 10
days (or at least after a given predeterminable past date) it
should react by marking that msg as old (i.e. the BX, PX state
setup in xfbb) and then deleted at next time expiry process.
