All files suddenly have a 1 hour newer "modified" timestamp??
I regularly back up most of my files using robocopy using the mirror function.
Usually this is quick as it only copies the files that have changed since the rpevious backup.
I haven't noticed anything in the past days, since I most frequently backup to another SSD so it is very fast no matter what. But to my horror, when today I decided to backup to a relatively slow USB stick, it began copying everything anew!
I suddenly realized that it was because every single file on the USB-stick was 1 hour older than all the files on my SSD.
The last time I backed up to this USB stick was about one week ago, so something must have happened in the last week to set the modified timestamp of every single file on my SSD one hour later than they were before.
What could possibly be responsible for this? I don't recall playing with the date-and-time settings in Windows, but...
And why should it change the timestamp? I could maybe understand Windows interpreting the timestamp differently, but then surely it should also interpret the files on the USB-stick as having the same timestamp. So it seems that every file must have been individually touched?
