Now i looking for a way to use it to update system time Just write a small tool to map the local timezone from the IP lookup to a timezone name (such as Europe/London) and write it to /etc/timezone. You could do that with a short ifup script. That said, for headless appliances working in UTC is absolutely fine, and for user-facing devices it's perfectly acceptable to ask the user what the timezone is, as your geo-IP lookup might be incorrect anyway.
