I am running debian. Sometime in the past month, when I received a kernel upgrade and also a tzdata upgrade, I noticed that the time was wrong on my system.

Today, I saw (apt list --upgradable) that another tzdata update was coming. Before I ran apt upgrade, I checked the following:

/etc/localtime -> pointed as shortcut to correct timezone
/etc/timezone -> contained the correct timezone

I watched the apt upgrade run. When it came time for tzdata to reconfigure, it said:

Current default time zone: 'America/Indiana/Indianapolis'

Which is wrong.

/etc/localtime and /etc/timezone were both now pointed to Indianapolis, which is wrong and not what they said right before the upgrade.

So I ran dpkg-reconfigure and got it fixed again.

Out of curiousity, I also ran dkpg-reconfigure and then selected "cancel" without making any choices. Guess what? tzdata set me back to "Indianapolis"!

This is happening on every debian/devuan/raspbian system that I have, and it started happening sometime during the past month or six weeks after I received a kernel/tzdata update.

I thought the time zone was saved in the two above places in /etc. Is there some other place that tzdata is reading from that I need to look at so that, in future, whenever tzdata gets updated I don't have to remember to go back and manually fix the time zone each time?

Thanks!
