"Last Updated" time is confusing

[Alan Pope 🍺🐧🐱 🦄]

I flashed my phone cleanly yesterday 2013-09-12.
Today I thought I'd check for updates in system settings.
It checked and then came back saying:-

"No software update available
Last updated 2013-09-10 22:27:20"

Two things confuse me here:-

1) I didn't update it on the 10th, I updated on the 12th.
2) I don't really care when it was last updated, I care when I last checked for updates. I might like a version number in there perhaps, but knowing when the build was made (which I assume is what 2013-09-10 is referring to) isn't interesting to me as a user.

For me it shows when I flashed the build, retrying to check for an update doesn't update the time I last checked.

Thanks Alan, so what you are describing there are 2 bugs:

1- is an issue with ubuntu-system-image (that's the service providing the update date info)

2- is a design choice, you should probably open another bug about that (I discussed that with mpt earlier in the cycle and he said the date displayed should be the date when you installed the current image)

(see https://wiki.ubuntu.com/AboutThisDevice?action=diff&rev2=8&rev1=7 for the design discussion)

The "last update date" is currently defined as the mtime of /etc/system-image/channel.ini if it exists, falling back to the mtime of /etc/ubuntu-build. You're right that this won't be the time that the image was created, not when it was laid down on the device. If design thinks that the latter is a better time to use, then what I'd probably have to do in s-i is write a file that encapsulates the time just before the reboot to apply the update. Or conversely, recovery could write this file (that's probably a better idea).

I'll wait until design gives us the decision before making any changes in the client, or suggesting changes to recovery.

@Barry: what happened to bug #1215943, what you described seems inconsistant with what we decided there...

(the "about" panel gets the right date by reading the timestamp btw)
