[SOLVED] BIOS time issue

Post#1 by pco » 29 Jul 2017, 20:48

I am working with my first installation of porteus. I am having an issue with the time.

I set the bios time to the local time (America/Detroit). I configure Porteus to use timezone=America/Detroit and load from saved file and burn to drive. After Porteus 4.4.0 boots, the bios time is shifted forward four hours to GMT. (I have a slow 1.5 Mbps internet connection for the kiosk.)

I want my kiosk to turn on a a certain time based on the bios time. Currently I have shifted the time by four hours (America/Detriot is four hours behind GMT), but I am not sure if I am seeing a bug, or if I am not understanding that Porteus uses only GMT even with the time zone set.

Hello pco,

If you want to keep the BIOS time (local time) then you need to set the time zone to 'Factory' and point ntp service to some non existing server. Please use these two parameters:

Code: Select all

timezone=Factory
ntp_server=fake.server.org
Let me know if this helped and i'll add this answer to the FAQ.

Thanks
Please add [Solved] to your thread title if the solution was found.

Thank you. It may be just as easy for me to work with GMT, because with either setting I would need to make an adjustment when our local daylight savings time changes. It is OK for me to work with GMT. I was very confused when the BIOS time was changing. But now that I understand that this is intended, I can set the BIOS on my machine to boot according to GMT.

However, I will give your suggestion a try and respond with the results for the benefit of other users with the same question.

Yes, the configuration by fanthom in #3 does work for me. However, I decided to let Porteus-Kiosk reset the BIOS time, because either way, I need to reset the boot time when our local time changes.
