I believe you may be able to reset your XBOX ONE date by disconnecting from the internet and then changing your date in offline mode and then reboot your gamedisc and play the mission offline and see if it pops after going back online...
It should work if you have the MCC in disc format not the digital content...
Thanks for your time...
Hours after posting this solution, I tried it and it worked...The Cheevo pops only in the SNAP Achievements portion...But yeah, it woked...
Please remember to "Hard restart" and to "Forget Wireless" before Hard Restarting...
Also a side note: Go straight into a ODST game in the "OFFLINE" mode and finish a mission. Then back out using the XBOXONE Center button and go back into settings go back online and the achievement pops in the SNAP Achievements section. Nevertheless, it pops and there you go...Thaanks...
