Oregon time zone bug patch

[Scott O]

This works on my F900BT with the 3.1 upgrade from viewtopic.php?f=34&t=25751 and a few other mods. I hope others will try it and tell us if it works for them. I would think this should work on other units as well.This puts all of Oregon into the Pacific time zone.

 

If you're not familiar with moving files to and from your unit there's good instructions here viewtopic.php?f=64&t=26446 and in lots of other posts.

 

The file tzinfo.bin which is in the data.zip file from My Flash Disk\APL2\iGo needs to be altered or you can try the one I've altered which I'll attach. Since this forum does not allow files with the bin extension I'll rename it to tzinfo.txt and you will have to rename it to tzinfo.bin after you have downloaded it.

 

I extracted my data.zip with winrar, replaced the tzinfo.bin file and repacked it and it worked fine.

 

I also opened data.zip with winrar and then opened tzinfo.bin, using Hex Editor Neo, from within the winrar window, altered the file and closed Hex Editor then winrar clicking yes to keep the changes and that worked fine too.

 

Hex Editor Neo is a free program available here http://www.hhdsoftware.com/Products/hom ... -free.html

 

Here's what I did.

 

If you open tzinfo.bin using Ida Pro near the end of the file you'll see lines like this (I've added my interpretations)

Here's what some of those same lines look like in Hex Editor, assuming the picture I posted shows up. I've circled the numbers you need to change. Click on that 4d, right click and choose edit cell and type in 7f. Don't try to delete the 4d, that won't work. Just overwrite it. Then close Hex Editor, click yes to save changes when it asks and you're done.

 

 

 

I think that covers it. It worked for me.

Just a bump to let folks know this worked on both my F90BTs with 3.02 and Diaftia 2.3 + MSN. Amazing the difference a single byte can make.

 

Moderator, please sticky. Modders, please integrate in your data.zips and note it in your release notes, please. Us granola-lovin' Oregonians will thank you.

Anyone think this will work for TN? I have my time set to Auto and my time displayed is the actual Easter Time when I am in the Easter Time Zone in TN. But when I navigate anywhere in Eastern TN is shows my arrival time as Central, but subracting an hour. When I get to my desination it will display current time of 3:30 pm Arrival time 2:20 pm. Any ideas?

If you change the 94 that is highlighted to 8f it should make TN all eastern time. If you live in eastern Tennessee maybe that would be better for you.
