Two Telemetry reports with negative uptimes

Telemetry occasionally reports negative uptimes.

Similar to bug 670008, but the bug is still present in Telemetry reports. See attached reports from a Dec 29th and Jan 11th build.
Could be bug 722625, general corruption in saved telemetry file.

It seems that there's no serious checksumming going on here.  Bits could be flipped anywhere, including in the user's RAM.
Xavier - I would like to gauge how prevalent this issue is - and if it is still an issue. Can you please check how many pings in recent days (recent for whenever you get to check) include negative uptimes?
This is still present but it's a pretty minor (negligible) issue in the numbers.

9/10/2012 => 401 out of 3,500,553 submissions had a negative uptime
9/11/2012 => 324 out of 3,282,940 submissions had a negative uptime

For what it's worth I'm only seeing it happen in release or beta channels.
Looks like we're talking about roughly 0.01% of the population. I don't think this is worth the time to investigate at this point. I'm going to resolve as wontfix.
