Why does the time recorded through date/time question is different from the time reported in GPS question?

Last Updated: Sep 09, 2016 12:26PM EDT

An Android tablet has its internal clock. That clock is set based on specifications of the tablet manufacturer and on the user settings. For example, the tablet clock can be synchronized to the network time, or can be set by tablet users manually.

The time reported in GPS question comes from the GPS signal provider. We recommend acquiring the GPS signal through satellites disabling the wifi coordinate services. However, geographic coordinates might be acquired through wifi. Survey Solutions records satellite time for the GPS coordinates received through satellites. When coordinates come from wifi or 3G, the time of the wifi router will be recorded as a time when GPS coordinate was acquired.

In general, we cannot guarantee that the time recorded through data/time question will coincide with the time recorded while getting a GPS signal.
