- updating system with local time
Re: updating system with local time
toggle quoted messageShow quoted text
can't write it to /etc/localtime ... it's a read only system.
There is an environment variable named TZ, when ever it is changed, local time is changed as well.
Is there a way (by script or cron job) to set the way system will update as well?

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.
