Incorrect timestamps in GPX files

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a log.
2. Make sure GPX export is enabled.
3. Export.

What is the expected output? What do you see instead?
Timestamps in the GPX files have the format yyyy-mm-ddThh:mm:ssZ. Upon closer 
examination, it turns out that the timestamps use local time, whereas the 
trailing Z suggests they are in UTC. Fix: either append the correct time zone 
(e.g. Z+01:00 for UTC+1) or write timestamps in UTC.

What version of the product are you using? On what operating system?
0.7.9 e561940 on Cyanogenmod 10.2.1

Please provide any additional information below.
Precise timestamps are needed if the GPX file is going to be used for 
correlation with other data, e.g. for geotagging photos taken with an oldschool 
digital camera. (Which is my use case, as I feed both OSM and openbmap with my 
logs.)
