Exporting to KML/KMZ/GPX with different UTC offsets

Re,

I flew across Europe from UTC+3 to UTC+1, so my GPS track contains a track for 3 time zones. I'd like to export data to 3 separate files and apply different UTC offset to each.

What I did was export everything to Table, view the track and determine where I crossed timezone borders. I have the following data:

Record 3: UTC+3
Record 4914: UTC+2
Record 7145: UTC+1

Now I just have to figure out how to split my whole log into 3 parts so that I could properly apply the time offset to each. Any ideas? :) 

Thanks.

Right now the only thing

Right now the only thing comes to mind is to export 3 .CSV files, each with a different offset. Then edit/merge them and convert to .KML/whatever using GPSBabel.

Any more efficient ideas?

Since you already have the

Since you already have the record numbers, you can use these record numbers in the common filter.  First filter from 3 to 4914, then from 4914 to 7145 and then from 7145 to '0' (=no limit).  Chang ethe UTC settings in between exports.

Ah, "rec. nbr" in the Common Filter->Other. Didn't notice that right away.

Thanks.
