+Residence events are called "residences" in [VTrack](https://github.com/RossDwyer/VTrack), and are generated using the `RunResidenceExtraction()` function. 
 
 As of VTrack version 2.10, it looks as though VTrack assigns the local time of the user's computer to datetimes. As detection data are typically downloaded in UTC, mort assumes that the datetimes output by VTrack are actually in UTC, rather than local time. Users will receive a warning when using VTrack residence events:
