MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
I use an old phone purely for mapping, then manually upload the gpx file to strava. But it alwyas ends up an hour out of sync.
Yesterday, I started at 10:16, this is the first section of the gpx:
[i]<?xml version="1.0" encoding="ISO-8859-1"?>
<gpx version="1.1"

Uploaded to [url= https://www.strava.com/activities/406491993 ]strava[/url], it shows a start time of 11:17, so is out of sync with everyone I rode with. What's going on?
Your phone knows where you are and what time it is, but could it be set to the wrong time zone?
Nope, set to BST.
It seems to happen every time I use that phone now, weirdly, it never used to.
The Z in the timestamp denotes Zulu time, ie GMT. MMtracker seems to have taken your BST time and recording as a GMT time. Strava then thinks it needs to add an hour for BST.
try deleting all the Z's in the GPZ and see if it fixes it. Notepad++ should allow you to do that pretty easily.
Just remembered how funny your electronics were. It it because you went near County Durham???
Its a bug with MM Tracker, I've noticed it myself. GPX files should always have the time in UTC (or GMT), but MM Tracker seems to record in the local time. Unfortunately MM Tracker is now discontinued, so its unlikely to be fixed.
You can fix this by processing the files with GPS Babel. If you look in Filters, there is an option for 'move'. So you can tell it to shift all of the times by 1 hour. http://www.gpsbabel.org/
Or just use another Android app to record a track. You can have another app running in the background, to record a track, while you use MM Tracker for maps.
Tried deleting all the Zs, deleted the original strava record (and all my kudos 🙁 ), uploaded it and it ended up the same.
Moved it in GPS babel - that did it, Flyby's now make sense.
Thanks
