※We don't have any time difference data in our app.
We have been inquiring about time differences of each city to iOS.
Therefore, “World Clock” shows you the time of iOS.
As a result, depending on the version of iOS you are using, the exact time may not be displayed.
If you find a time lag in our app, please confirm default "Clock" app on your iPhone.
If the time in "Clock" app is the same with the time in our “World Clock”, it means that our app is running normally.

※Abbreviated name of time zone was originally researched and added.
