How to sync up time between cameras?

[Photongraphy]

I only knew ways to edit image for image - your reply is very helpful. Thank you!

I had an event yesterday (only a couple of hours long). [...]

The GH6 had drifted almost 2 minutes forward, while GH5M2 had shifted about half minute, since I synced them up manually about three months ago. I didn't check recently but my FZ2500 doesn't seem to drift as much.

Nikon D7200 was synced up more than a year ago and it had drifted 9 seconds.

Why did you go through that whole EXIF routine when you could have simply set the time on your cameras before the event?

Your worst offender is the GH6 which drifted 2 minutes ahead over three months. That equates to a negligable 0.16 seconds over the course of a 3-hour event.

I tried to set both cameras at the same time manually, but it still causes few seconds difference between the two. When I set the two cameras to the same time, say 15:42:06, and click OK at the same time, the first few photos from both cameras show a difference in time.

When I change cameras in quick succession, and sort the photos on date taken, the sequence of event is not right.

GPS only works because of the phenomenally accurate clocks it uses. Every receiver gets the benefit of a very accurate clock as a side effect while acquiring its position

It's not a "side effect" all a GPS receiver gets is time signals, position is derived from these.

That's strange. Have you also tried the method outlined in my first response, in which each camera is set separately around a clear minute mark? Maybe that will do the trick.

I have not tried. I will.

If I understand correctly, you're saying I should set each camera's time at a minute mark and zero seconds, correct?

I don't really care for small differences with real time on the clock. I am only interested in the two cameras' times being in sync, so that all photos can be sorted in proper sequence.

Thanks.

PS: As a sidenote, I learned that the automatic time setting using WiFi and app on Olympus cameras works better. That is good. I also learned about benefit of GPS in maintaining accurate time, though none of my camera models have built in GPS.

I hope I didn't mislead you. While GPS is absolutely capable of keeping accurate time, I've never seen a single camera use that capability. Built in or otherwise. A shame really.

OK. Thanks.

Using my method they should all be in sync as well as keeping actual time.

Oly's own E-M1x derives its time from GPS (if its "Auto Time Adjust" setting is On).

As do all Olympus compact point & shoot cameras that have GPS.

Well thank you both for telling me something I didn't know!
