Guess I'm OK, then, since I've disabled the internal GPS on the Samsung and
accept GPS data from the CAI 302 via Bluetooth.

It doesn't seem to have anything to do with XCSoar or the UTC offset.
XCSoar
is fine. It's something about the specific device and probably more
specifically the Broadcom GPS module.
Mine is a Samsung SGH-1897 phone with Firmware 2.2 Froyo.UCKB1 In the
discussion I
mentioned, they are speculating something in the Broadcom GPS module
firmware is out
of sync due to the leap year, so it is feeding bogus information to
the NMEA data
stream. It affects any other apps that use the GPS besides XCSoar. It
may only be certain specific models of the Samsung devices and
certain specific GPS receivers that may be in them. But it would be
worth it
to examine your IGC files if you are using a Samsung device with an
onboard Broadcom GPS
module before you make a long flight and then can't use the IGC file.

With XCSoar 6.2.4 I've found that my GMT offset (-7) resets to zero every
time the system is restarted. Maybe that only happens with a power cycle
on
the Samsung. Is it possible your GMT offset is not correctly set in your
software? I think if my GMT offset is set at zero, the date will be
"tomorrow" since it *is* tomorrow in Greenwich.

Also, I download my IGC file from my CAI 302 (serial to Bluetooth) so I
haven't tried to upload a log generated by the Samsung. BTW, mine is a
player, not a phone.

I made a flight on Saturday, Jan 28 in Calif. using a Samsung Galaxy
phone with XCSoar 6.2.5.
The file would not process on the OLC. After examining the IGC file,
it was recording the date in the file one day ahead of the actual
date, i.e. it was recording Jan. 29 (and Jan 30 after 0000 UTC). My
first thought was it might be something with XCSoar, but more research
revealed it is actually a bug in the firmware on Samsung Android
devices using the Broadcom GPS module. Possibly related to the fact
that it is a leap year. The bug started showing up on Jan 1, 2012.
It affects any other GPS apps on the device.

So if you are using one of these devices, watch out, your OLC files
may not process properly. There is some discussion of it he
