Also, though time usually moves quite slowly in the MU, roughly 1 year for every 5 in the real world, there were, according to Marvel, 2 time jumps with Secret Wars. One before the final incursion, and one after the event ended, to sort of massage any post-reconstruction weirdness, both were several months. I know the second one was 8 months, not sure about the first, but in any case, there's a year or more right there, which lines up with the above, most of it just happened off panel.
