Need HELP getting a timestamp added to your 360 achievement you unlocked offline because...

If you unlocked those achievements offline, a timestamp cannot be added to the achievement; it must be unlocked online for that.

No, since you earn the achievement offline, there is no "timestamp". I have no idea why they chose to do this, but it's most likely because you can change the Xbox's time and date to whatever you want while offline. It would not make sense to unlock an achievement
on 12/12/12 since that's in the future...

As others have said, OP the only issues tend to fall with achievements which should need to come online being earned offline.

Order of achievements isn't an issue if they were earned offline because no timestamp is applied. If you take a look at my Achievements for Halo Reach on Waypoint or True Achievements my order is totally off for the single player achievements because I earned
them offline with no timestamps.

Shouldn't be an issue (unless you've done something wrong like modding)

Hello Phoenix,

The information provided regarding whether the achievement will update is set information, as there will be no way to update the timestamp of when the achievement was unlocked.

As the Ambassadors stated, this would be due to the offline disconnection that occurred not allowing the correct timestamp to be applied.

If there are any other questions, please feel free to reach out and we'll be right here to answer your questions.

Best wishes!

Hi byNeizo,

At any point in time did you unlock these achievements while offline on the Xbox 360?

Achievements are synced over Xbox Live so if you unlocked achievements on the old Xbox 360 while offline, then your progress will not be reflected if you get a new console or on True Achievement website.
