Nicholas, you have Lightroom? It is very easy to do in LR using the metadata section. I'm away from my main computer but could walk you through it or I imagine you could google/youtube it and get a better explanation.
Perfect - I’ll poke around tomorrow and if I can’t figure it out, I’ll reply to this thread.
thank you
Nick
Our vacation spanned the weekend of the most recent time-change - March 25th/26th for those here in the UK and across much of Europe....
We left home the preceding Wednesday - equipped with smart watches and phones, a wifi-only tablet and my various cameras, all set to UK time, at that stage GMT.
Flew to Spain, where our phones automatically pick up Spanish time (GMT+1) before we're off the plane. Our watches sync to those. Didn't bother to advance the cameras, so pictures are an hour "behind" local time - and don't know how to change the tablet, which ignores any time info in overseas wifi.
Come Sunday morning (and that winter-to-summer time change) and before we wake the phones have automatically advanced another 1 hour (to GMT+2); we re-synced our watches. Tablet and cameras are now all 2 hours "behind".
Fly back to Britain: phones automatically move to BST (GMT+1) and we nudge our watches into doing the same. On reconnecting to the airport wifi, tablet sets itself to local time... so now only the cameras are wrong, but by only an hour.
Arrive home and the next day make the usual round of corrections - advancing cameras, older watches, household clocks and the one in our elderly car... and, as I've done twice a year for decades, marvel at how the simple timer on our domestic heating system knows just how and when to change!
******************
Further thoughts, in no particular order....
1 Next year, do as we did in 2022 - and time our break to avoid all this extra hassle!
2 Get a new phone with better photo capabilities and leave cameras and tablet at home.
3 Do any of the camera makers' phone apps apply the correct time and date to cameras, in the way the apps of our £25 knock-off watches do? If not, why not?
4 Another instance of how useful it is that Lightroom makes correcting such errors so easy!
****************
Hope you'll be able to fix this without too much trouble,
Peter
