But not necessarily the same time. For instance, some cell systems run
on GPS time, but the carrier may keep records in UTC, since it's the
legal time in most jurisdictions. A phone might time stamp using either
(Google has a years-old bug in Android which lets it use GPS time and
not UTC). So, different devices on the same network may not be in sync.
