The proper STR for this bug is mentioned in Bug-905972 happens in Master V1.1.0 hd.

* Reproduction steps:
  1. Set up the cost control/Usage app
  2. Browser a webpage
  3. Using card view to close Usage app
  4. Changing the system date to any future date
  5. Browser a webpage
  6. Changing the system date to current time
  7. Open Usage app and tap reset button-->Reset operation will not work
  8. The Red and Green dots will not be shown(Bug-886276)

This bug happens changing the system time back and forth after configuring the Usage app.

Due to the BE state for 1.1 this is an expected behavior. The situation of changing big periods of time is very unlikely and when the situation is about changing for a short periods of time (around 1 day), the issue disappears as soon as present day surpasses the future date.

Dear Salvador, 

Check from code, it seemed when reset data usage, it doesn't clear  the data, only reset nextReset and lastDataReset value, so the usage data in future date will always be calculate. Is it right? 
If someone change the year number to next, and generate many usage data, he will unable to use this app correctly until next year. Is there any way can remedy it?

The BE reset wipes all the data so I can loose those samples related with another SIM. This is the reason I never call the real reset() method.

Yes, this is a problem. Thank you for spotting it. Let me check if there is a workaround for this and it there is not. I'll file another bug for this.

Thank you.

Dears, please also think about roaming case, if date/time of device sync with network, the statistic data usage may be inaccurate and confusing.

And I think user care about data usage when phone linked to 2g/3g network, we can't ignore the situation that phone with wrong date.

I reopen it so we can continue to discuss here.

If you're synching with the network, the difference will be one day at most. For one day, results are mostly correct and intelligible.

And we don't but not for v1.1 so I agree with you in nominating for koi.

> I reopen it so we can continue to discuss here.

Once 1.2 new API lands new bugs will be open to refactor parts of the Cost Control application to use the new features but if you think we need this to discuss... no problem at my side.

Thanks for your response, I agree with you that it should be refactored in v1.2 according to better solution.

I appreciate your efforts and hope seeing it set koi+.
