Accessing historical versions of the cloud copy of the dive log

[Willem Ferguson]

For data security when something wrong has happened to a dive log, it 
would be invaluable if one could request "Open die dive log as it was on 
October 1st 2018". Is something like this in principle possible with 
git? From browsing the Internet it appears that git stores only uses 
version numbers, not timestamps. But since, in the cloud repository, 
only a single file is updated with each push from subsurface, it might 
be possible to get the timestamp of the dive log for each node in a 
pretty linear tree structure ???

Git is still a bit of an untamed animal for me, but the sort of problem 
that could arise is because git stores trees, not necessarily linear 
sequences. In theory there may be several valid tips of branches on 
October 1st 2018 within a single cloud repository. But I suspect the 
dive logs on cloud are pretty linear.

I have no idea what is possible.

Kind regards,

willem
