In my android app I read GPS data and GPS time. For some reason GPS returns tomorrow’s date. Anybody knows why?

I get data like this: (it was always good). Bug in 4.0.3?!

position.GPSTime = new Date(loc.getTime());

enter image description here

EDIT

I keep ALL times in UTC. This app being in production for 1 year – results I’m showing from 1hr ago and you can see they are UTC times. On a left – time reported by device and on a right – time from location service. I’m not confusing anything, those dates usually 1-2 seconds apart.

EDIT 2

See shot from my debugger from my phone!! Took 2 minutes ago (~10:10 AM CST)

    GPS time is being expressed in Coordinated Universal Time. The reference time is the time in London. You’re getting confused with your local time which is in a time zone that’s behind UTC time by 1 day.

    After much troubleshooting and research, I came across this Code Google article Issue 23937: GPS Provider : android.location.Location.getTime() returns wrong UTC timestamp on 4.0.3 / Nexus S which seems to describe the same symptoms.
