BUG? "Add to version history" function not behaving as expected

When saving using “Add to version history” for a file, the time-stamp of the newly created version is often not “Just now”, but many minutes ago.

I could understand this if i hadn’t made any changes since the time it’s using for the time-stamp, but this happens when i’m actively editing the file.

For example today when using “Add to version history”, the time stamp was 28 minutes earlier, and i’d been constantly editing the file in that time.

When this happens if you “Add to version history”, it creates another version in version history with the correct time-stamp of “Just now”, but i shouldn’t have to do this.

Anyone else seeing this happen?
