The current tzdb release (2018e) already has North Korea using the same time as 
South Korea, so tzdb is already synchronized reasonably well. Please see the 
announcement here:

Although there is a delay before this release's information hits everybody's 
cell phones and computers, it's not clear how the tz project itself could 
shorten that delay. Typically, most of the delay is downstream.

If a government gives only a week's notice about a change, as North Korea did, 
the delay means that cell phones and computers will likely not be updated in 
time. For more about this and how governments can do better, please see:
