If you were to change the time on your device to 2010 in 2023, it would depend on how the trophy system in question functions.
In some cases, the trophy might be tied to the specific year it was achieved or earned, so it would likely display as 2010. This is because changing the device's time doesn't alter the actual date the trophy was obtained.
However, some systems may be designed to dynamically update the year associated with the trophy based on the current time and date settings on your device. In that case, if you change the time to 2010 in 2023, the trophy might appear as 2023.
Ultimately, it would depend on the specific implementation of the trophy system you are referring to.
