16. A computer-implemented method comprising:
determining a first time using a clock at a first device;
determining a first location of the first device;
receiving, at the first device, first data from a second device, wherein the first data is indicative of a first transmit time of the first data;
determining a first reception time associated with at least a portion of the first data;
determining, based on the first data and the first reception time, first time correction data;
determining a loss of timing information; and
based on the loss of timing information, determining first corrected time of the first device based on the first time and the first time correction data.
