My GW-60 shows the correct time (GMT +2 set in the watch).

But when I look at my session in the day ranking (the time figure) they are 4hours early?

Example:

I actually ended that session just after 18h00 but it shows after 14h00.

How do I correct for this?

Found a solution:

In GpsAR Pro I used the time shift function to compensate for the difference.
