Activity time for Walking

Hi,
My walking activity which was synced from Garmin Connect has wrong time.
In Garmin Connect it was 6:08:46, In intervals 3:39:04.
It was uphill hiking, so pretty slow sometimes. I think it still should be 6 hours, not 3:39. Because I didn’t paused it.
If you need I can share my original file from Garmin.

Intervals.icu displays moving time by default and looking at that hike there was quite a bit of stoppage time. So I think thats it.
