NTP tracks UTC. Paraguayan "local" time is defined as a certain offset
from UTC, and what has shifted is the offset. NTP is in no way involved.

You need to tell your operating system this. On Windows, there was once
a time zone editor in the Windows 95 Kernel Toys. On Unix, /etc/localtime
is a copy of or a soft link to a file under /usr/share/zoneinfo and while
I don't know the file format, it's bound to be described somewhere. You
could also ask the people who maintain those files for an update, or the
president who broke the old one.
