David Smith has struck again:
Here’s the easy one for those of us not quite up to running the script in terminal. However, after applying the fix above, I did run this in terminal and validated the dates for 2007
zdump -v /etc/localtime | grep 2007
Worked for me. Says it works for 10.0 10.1 10.2 to 10.2.8
just copy and paste into the terminal, and hit the return.
This niffty command tool will work for those that the packaged DST installers don’t
Update: There is an installer for 10.0 to 10.3 from here.
