1. A system for aligning event data, comprising:
a first recording device configured to perform first operations comprising:
maintaining a first time;
recording first event data during the first time, wherein the first event data is marked with the first time;
wirelessly broadcasting, by the first recording device, a first alignment beacon comprising a first alignment data;
storing the first alignment data in a first memory of the first recording device, wherein the first alignment data is stored with a first current time of the first time;
a second recording device configured to perform second operations comprising:
maintaining a second time independent of the first time;
recording second event data during the second time, wherein the second event data is marked with the second time;
wirelessly receiving the first alignment beacon from the first recording device; and
while recording the second event data, storing the first alignment data from the first alignment beacon in a second memory of the second recording device with a first current time of the second time, wherein:
the first current time of the first time is related to the first current time of the second time by the first alignment data;
the first event data is related to the second event data by the first alignment data;
the first alignment data is separate from the first event data; and
the first current time of the second time is different from the first current time of the first time.
