Display GPS time/date to help with photo geotagging

[GoogleCodeExporter]

It would be nice if mytracks had a screen that displayed the GPS time/date.  
This is helpful if you're geotagging photos, since you can take a photo of this 
screen to match up the GPS time with the camera's time.  For details of this 
workflow, see: 
http://geosquan.blogspot.com/2010/03/geotag-photos-with-android-phone-and.html

You can download the "GPS test" app to do this, but it would be nice to have 
this included as part of mytracks.  

If you're a developer, are you willing to implement this yourself?  Yes 
(theoretically, since I don't know if I'd ever have time.)

Nice. I've been using a similar workflow with Apple's Aperture.

I'm not sure what you'd like though - the GPS date/time is basically the same 
as the phone's, in UTC timezone. AFAIK this is specially true if your phone is 
GSM, as GSM synchronizes TDMA slots with the GPS clock.

I think with more and more phones getting better and better cameras, it would 
be great for mytracks to automatically add photos taken while tracking to the 
recorded path. I'm not sure that all formats would support this, but I think it 
should be fairly easy in KML. For any format that doesn't support it mytracks 
could just report that by choosing to export to that format photos will not be 
associated with the track, but that they will still remain on the phone.

I think this is a perfect fit for a separate app which talks to the mytracks 
service - e.g. a camera application which calls mytracks every time it takes a 
picture. Not sure if there's an easy way to detect that the main camera app 
took a picture, I'd need to check.

The approach I took when I started 
http://code.google.com/p/mytracks/issues/detail?id=17 was to have taking a 
picture part of the my tracks app.  IMHO it worked pretty well.  The only 
blocking issue was getting the upload to picasa working properly.

The use case I'm thinking of is when the phone's clock is inaccurate.  In this 
case, seeing the GPS clock helps synchronize with the external camera's time.

This use case comes up in a few cases:
a) When I was traveling to a foreign country and didn't have a phone plan, so I 
wasn't getting the phone network time.
b) When the phone network time is wrong, which does happen.
c) When the phone is set manually - menu > settings > date & time settings > 
uncheck automatic.

But maybe this is a corner case...

Right. Makes sense, but it is indeed an uncommon usage, so how about this being 
an optionally-displayed field in the customizable stats screen (meaning this 
would be the same as issue 24)? If you think that wouldn't be good enough let 
us know.
