The app idea and procedural seems ok but it fails retrieving databases to update servers. It's a fault or its just me? (as far I know, there's no firewall here) Thanks!
Had to use another app, but it didn't change the time for my calendar's events. This one works nicely.
Yet another perfect app. Thank you!
It cannot get any new version, it fails. It seems it cannot connect to the server which has the updates.
Updates not only tzdata, but also ICU information, which is a common cause of timezone issues
