I have a server where I and 2 friends are using it.
Recently a friend flew to Thailand. When arriving there it sent a position with a weird timestamp (2017-10-08), after that all timestamps of locations are ok, but now it shows the wrong last location of the friend on the map, i.e. not the last received locaiton but that with the timestamp in the future.
How to fix that? What could be the cause of the weird timestamp?
Most likely it's a device issue. It's very common for cheap Chinese devices.
The easiest fix is to re-create device. If you don't want to lose the history, you can manually remove "future" record, but you need to have some SQL knowledge to do that.
