I've not seen a description of the real problem, only that it needs to be small and cheap.
Cheap I can do (as in free) since I have too many time code generators/receivers. IRIG-B is a 1 KHz audio time code designed to be recorded for a time reference. The Datum units are 1.75" rack-mount boxes weighing 10 pounds or so, about 16" deep. Each box has a time display, which is settable for a generator. It would be possible to transmit the audio to the cameras using cheap walkie-talkies. Each recording could have its own time code receiver to display the time from the video, if necessary. Otherwise, the generator box can act as a receiver. The units use small-scale integrated circuits from the '70s. It is possible to rewire them. Let me know if this is useful. Shipping from Minneapolis, MN 55438, or the flea market on the 15th.
