Flame b2g - prerelease
build 20150414002504

-open a app like telegram
-look at the time in the bar at the top of the screen
-pull down the notification screen
- look at the time there

it is not the same time

the same time
See the screenshots i took a few weeks ago right after each other, i still exist in the build of yesterday
There was something like bug 1107441 about this.

This happens with the automatic date&time setting set? Does it matter which app you open (telegram)?
yes automatic time an does not matter witch app, the screenshot i made are with the emailapp.

It looks like the bar shown in the app is not refreshing. also i.e if you turn off wifi the wifi symbol goes a way in the notification screen but not in the bar inside a app (just test it again while i was in the time settings)
Seems like the status bar still has some refresh bugs.

I can't reproduce on the latest master.
Tim, can you give more details about how to reproduce? Is it happening right away after booting? If no, how long after restart? Is it triggered by a particular event? I need anything really that can help me to pinpoint the issue.
Flags: needinfo?(bugzilla)
I can confirm I saw some similar stuff happenning within several apps, and not only with time but also wifi, for instance. That was on master with a build which was roughly a week old (~april 10th).
Do we already have a logging mechanism in place?
blocking-b2g: 2.2? → 2.2+
Not yet, I put it on hold while Bug 1139470 got fixed.
It is tracked on Bug 1144126.
I'll resume working on if we can't get STR here.
I did a ota to build 20150416002504.

Opened telegram wait for a few minutes and then compared the time in the app with the notificationscreen. It appears  that the bar inside the app was frozen, even when i go ta a other app (mail) the time is not changing 


Opened  mail wait a few minutes and the same result. Even now (15 min later) the time show in the apps (mail, systemsettings, openwapp) stays of 15 min ago.

The only thing moving in the bar is de indicator of datatransfer, if i turn off wifi that symbol does not go away

It is even worser then when i first noticed it, first it reset when leave a app now it freeze
Flags: needinfo?(bugzilla)
I just noticed that the time is now just 1 min behind so it refresh at some time.
I cannot reproduce this issue with master & 2.2 pvt build.

@Tim, what was your previous version before ota? I noticed that Nexus 5 has similar issue with the older base image (android 5.0).

Let's get the logging landed in Bug 1144126, and then see if Tim can get us a logcat since we are having trouble reproducing.
I have several thoughts here.

1 - I think my comment in bug 1139470 comment 15 still applies. I don't know if in this case the value is < 0 or > 0, but still a value < 0 should not happen.

2 - I think it's now clearly proved that the counter is highly unreliable. Tel lme if I'm wrong here: the "freeze" of the statusbar should not last more than 1sec. OK, let's say 2sec. How about introducing a timer that forces the resume after 2 sec, if it didn't happen yet? Belts and suspenders.
Flags: needinfo?(gmarty)
I worked on a fix for Bug 1154800. Though that bug is very specific, the patch is likely to fix some of the status bar issues we have. I would wait a few days before resuming work on the event logger.

Also, Julien, these solutions seem really hackish and I'd rather work on the root cause than trying to fix the symptoms. If we don't, we may miss bigger issue affecting other part of the code. Let's do something like this as a last resort.
Flags: needinfo?(gmarty)
What seems hackish to me is the current fragile way of pausing/resuming using a counter. And I think the various similar bugs are all grist to the mill. Maybe it's time to revisit this unreliable logic.

Really, I think it's good enough to have a 2sec timer to resume the update (pauseUpdate would cancelTimeout existing timeouts). There is no need to be more precise than this. We don't care if the update could have been resumed after 500ms rather than 2sec.

And at least this logic would be rock solid.
Can QA reverify this issue on the latest build?

I cannot reproduce this bug on today's 3.0 nightly. I used email app for ~30 minutes, and a mix between other apps such as Settings, Phone, Gallery, Messages, Camera. I also tried to update icons on status bar by turning on/off wifi, data connection, NFC, bluetooth, and status bar icons and clock always match with utility tray's.

I was also unable to reproduce this issue when I updated OTA to the latest 2.2. I followed the repro steps from Comment 11 with and without 1 minute screen timeout, and changed wi-fi, airplane mode, Bluetooth, and data settings. The status bar seemed to displayed correct icons and time.
