How do I save my time settings?

[MrDitchy]

As I am unsure of what the path to proper timezone is how do I find?

You can list all timezones available with "ls -lR /usr/share/zoneinfo", it will show many cities/contries/provinces/states as well as standard GMT+x.
You can then choose the one that fit you needs/wishes ...

In my case, I'm always use /usr/share/zoneinfo/America/Montreal .

Thanks again. I tried "ls -lR /usr/share/zoneinfo" from root and got an invalid option but I think that was a typo involving a missing space between the "-lR" and the "/", so I explored the files and found my timezone . It is /usr/share/zoneinfo/Pacific/Auckland. So if I understand correctly from / I type "rm etc/localtime" then "In -s </usr/share/zoneinfo/Pacific/Auckland> /etc/localtime" 
Thanks for taking the timeout to help me, I don't want to break my OS over the timezone. I did notice that when the Pinebook Pro was restarted after a couple of days initially the time was correct and after a couple of minutes it reset it's self to GMT.
Thanks again
