You might be able to, but even then it is more likely to be a person doing exercise on a device with the wrong time zone than it is to be someone on patrol.

To reiterate: Strava isn't always on. These are activities people have actively chosen to log. The chance of it being someone out on patrol is... not high.

Having to actively log the data is interesting. I agree with your conclusion there.

However, GPS is primarily a very high precision time signal, from which the current location is reconstructed. Basically, a properly designed software would do the proper time zone adjustment based on that, so the data should ideally be in local time everywhere without exception. Everything else would be a bug in my book.

OK, but that isn't how these devices work.

Source: I've used lots of them and it's a real pain in the ass.
